You Need to Know | Glossary of Terms
This Library Research Guide will help you find a specific image to draw attention to, or help explain what you are saying in your paper or thesis. Your search can include pictures of paintings, sculptures, photographs, cartoons, clip art, multimedia and video. On and off-the-Web search strategies and some of the best Internet image search engines and sites are listed below. Note: Always look for permission from the web page's author or institution before using an image for a paper, online presentation, or web page. Sometimes permission will be granted on the web page itself, especially for clip art.

These words describe exactly what you are looking for. They are called "subject headings" or "descriptors" or "key words."
This will only bring back pages
with the words "mona lisa" or "monalisa" associated with
an image as in the name of an image file. Retrieving that file might also
retrieve the image itself.
If not successful, try again using
slightly different and creative wording.
Image: "miners hat"
Image: "hard hat" and mines
You can also shorten your descriptors
to catch variants of words. For instance, if you are looking for pictures
of children playing, you would might want to search for images using
the words children, children’s, child, child’s as well as for the
words playing and play. To catch all of these words in one
search, you can use the * symbol, like this:
This will find all images that
have a name beginning with "child" and with "play" that the search
engine has indexed.
Some search engines don’t have the
ability to search for text in image file names. In this case you can work
with the knowledge that most image files end with the string ".gif" or
"jpg". You could search for:

| It
is critical that you know that any use of an image you did not create requires
permission from its owner. You do not create an image by scanning it from
a book or magazine. That is copying, and it is illegal if you do not have
permission.
It is not possible to make a categorical
statement about copyright which covers all the pictures and other visual
resources found on the Internet. If you wish to use images, inquire about
the copyright status of the individual image. This information is almost
always available at the web site where the graphic materials are found.
Knowingly or unknowingly violating copyright notice can put you at
The copyright statements below offer a typical, generalized perspective of graphic copyright terms and conditions. The statements have been compiled from the terms described at ten major Internet image collection sites. |
COPYRIGHT MATERIAL PROVIDED BY OTHERS AND USED WITH PERMISSION
Graphic images include web graphics, photos, logos and other digital art, writings, text ,HTML, javascript or other material that you are given permission to display on your web site. Giving permission does not entitle you to claim copyright to the material in question. Permission to use someone else’s material does not make you the rightful owner or holder. Therefore, the copyright ("c") symbol that you put at the bottom of the web site only pertains to the content that YOU actually created, not to what was created by another and is being used with permission. Owner’s terms may vary, but it is always best to include text on the same page where the material on loan is being used to specify who the real owner is, and that it is being used with permission. To an extent, this would protect you as well as the appropriate owner as it would be notifying the public that someone owns the material. If you failed to properly protect someone else’s work that you are using and it turns out that someone else swiped it due to your misuse or negligence YOU may be subject to a claim.
"FREE" WEB GRAPHICS AND LINKING IMAGES.
Graphic images provided by "free" or "linkware" graphics sites are not public domain. These images, although provided to you for "free" (no money involved) are not being given to you in ownership. You are being allowed to use them if you comply with the owner’s terms and conditions.. Make sure that you comply with the owner’s terms and conditions. Make sure that you comply with the owner's terms and conditions in full when you use or display the graphics in question. If the owner says "don’t alter it", don’t alter it. If the owner says, only use for your personal homepage," only use it for your personal homepage. All the free images are for display purposes only and may not, under any circumstances, be sold, altered, or used for any type of personal or commercial gain. You may not display any graphics in any other graphic collection. The same applies to linking images or logos. They are still copyrighted by the owner and are usually only to be used for links to the owner’s web site. Again, in these cases the "C" symbol at the bottom of your web site only pertains to the content that you yourself created, not to the logos provided to you for links or the "free" graphics loaned to you to decorate your web pages.
THREE TYPICAL COPYRIGHT LICENSING TIERS:
WEB SITE LICENSE.You can use visual materials in a noncommercial presentation as well as in a non-commercial WEB site. All the free images are for display purposes on websites and personal computers only, and may not, under any circumstances, be sold altered, or used for any type of personal or commercial gain. You may not display graphics in any other graphics collections or off the Internet in any way, shape or form.
PRESENTATION LICENSE. A presentation is a personal or business presentation that you prepare and present for yourself or on behalf of your company, which conveys ideas and presents facts, opinions and information to others. You may use, present and distribute your presentations containing visual materials to others via computer (but not via the WWW or Internet), removable storage media or CD-ROM, so long as the visual material is contained only in your presentation and is clearly not intended to be downloaded or copied by users on a stand alone basis. Cartoon use is restricted. You may use a cartoon in a single presentation for up to one year. You must then renew the license for subsequent years or for any additional presentation you create. Cartoons and captions may not be cropped, altered or modified. No colorization is permitted. The trademark notice of the company renting the material to you must appear.
PRINT USE LICENSE For photographs, photo object and templates, a license generally grants you uses permitted under both the presentation and Website licenses plus uses in advertising, editorials, catalogs, brochures, reports, disposable packaging, book covers and educational text books. Typical licenses also allow you to use the image in screen savers, wall paper, electronic greeting cards, web sites, broadcast video, multimedia presentations and CD-ROMS, provided that the visual vendor materials is at a resolution not greater than 600 by 800 pixels and is incorporated into a design in such a fashion that it is clearly not intended to be downloaded or copied on a stand alone basis. Cartoons may be used in up to 1,000 printed newsletters, presentations or reports. After 1,000 uses, the licensing must be renewed.

| JPEG | Joint Photographic Engineers Group, a compression scheme for the JPEG File Format (JFIF), a common Web image format. Good for full-color pictures. Not good for text or line art |
| .JPG | If you only want images, try just looking for images files ending in ".jpg." jpg images are likely to be larger than .gif images because .jpg images don’t take up as much computer memory; they lose a little quality in the process, but not usually enough to notice with the naked eye. |
| Logo | Stands for "logotype," an identifying symbol, as for in advertising. |
| Lossless Compression | A file compression scheme that does not throw away image information in the process |
| Lossy Compression | A file compression scheme that throws away image information in the process, thereby Compression leading to a degraded image. |

MPEG-3 is a standard for CD-quality music and MPEG-4 is a standard for video telephony. |
| Multimedia | Refers to the simultaneous use of more than one type of media such as text with sound, moving or still images with music. |
| Pixel | "Picture element," the smallest addressable component of an image; one "dot". |
| PNG | Portable Network Graphics is replacing the GIF format to offer more capabilities. |
| Resolution | The number of pixels in a given area (the more dots or pixels the higher the resolution). Usually described as dots per inch (dpi) or pixels per inch (ppi). |
| RGB | Red, green, blue, the three additive colors that go into making up a full-color image on screen. |
| Streaming | Streaming data refers to multimedia files, such as video clips and audio, that begin Media playing seconds after it is received by your computer from the World Wide Web. The Media is delivered in a "stream" from the server so that you don’t have to wait several minutes or longer to download multimedia files. |
| Thumbnail | A small version of an image, usually no more than 2" on a side, used for previewing a larger image. |
| TIFF | Tagged Image File Format, a standard image file format that can be used with or without compression. Most often is used to save master versions of images. |
