Images and Graphics
Most sites on the Web today use images or graphics.
The two terms are generally interchangeable in a Web context. (Sometimes
a distinction is drawn between photographic "images" and
line-art "graphics." We use the terms interchangeably.)
The most important principles for images/graphics on IU Kokomo Web sites
are that they should be relevant, professional, optimized
for the Web, and legal.
The principles and guidelines here deal primarily
with static images, but the same principles generally apply to images
in flash animations, video clips and other multimedia presentations.

General graphics principles
- Professionalism and presentation are important.
The way your graphics are designed and presented is a reflection
not only on your Web site and its information and resources, but
also on the entity your site represents (your program or college),
IU Kokomo, and Indiana University. If you do not have experience with professional design,
we recommend that you obtain assistance from someone who does.
- Relevance is important. The graphics on your
site should be directly and obviously related to your site's content.
- Legality is critical. Site developers
must know, understand and comply with the rules of copyright for
images on the Web, as well as in print. The easy
availability of images on the Web, along with the anonymity of
the Web, can create complacency about image ownership and copyright
law.
As a general rule, if you don't know who owns an image, or if
you have not been granted express permission to use an image,
DO NOT USE that image. Understand that at IU Kokomo, Web site
developers, as well as the directors who authorize site development,
bear express and personal responsibility for all content of their
sites. Site developers/directors also bear liability for any breach
of copyright in all site content, including text, images and auxiliary
site features.
- An important corollary to legality is ethics
in the use of images and site content. IU Kokomo is committed to ethical
Web development. If you have ANY questions about the origin, alteration,
use or development of the content on your site, please contact
the Office of Communications and Marketing for consultation.
- Understand the regulations for using
IU Kokomo
logos and wordmarks on your Web site.
- If you require assistance choosing, obtaining, or using images
on your Web site, contact the Web Manager for
suggestions. You may also refer to the
online
image gallery (which is under continued development) if you
would like to use existing IU Kokomo images on your site.
IU Kokomo graphics standards
- Keep all graphics for each site together in the images
folder. The link paths in your site should be relative
(i.e. "images/graphic.jpg" or "../images/graphic.gif,"
etc.).
- Use good syntax for naming images: lowercase
letters, no spaces or extraneous characters except the "_"
character, short and descriptive file names.
- Avoid using background images (sometimes called
background gifs or tiling backgrounds). They are distracting,
and rarely add to the professionalism of a site's appearance.
- Avoid flashing or "animated" gifs.
With rare exceptions, these icons do not add to the professionalism
of a Web page/site.
- Avoid using cute or whimsical "clip art."
Graphics should be professionally produced and presented.
- Pay attention to colors. Your colors should
work well together, and should complement the site's images and
content. While you are not, at this time, required to use the
Web-safe color
palette, we do recommend that you optimize your colors for the
Web. The Web-safe palette provides a good way to do this.
- Use .gif and .jpg images appropriately for
the types of images on your site. While some browsers can read
.png and .wbmp images, it is not a good idea to use these formats
on your site. We recommend that you save your high-resolution
original images in an image editing program, and create 72 dpi
JPGs or GIFs for Web use. (A note on image formats: For
the most effective use of the relative compression algorithms,
JPG is usually used for photographic images, and GIF is usually
used for graphics with larger areas of common color. It is important
to note that JPG does not support transparency, so if you want
a transparent image, it will need to be a GIF. You can simulate
transparency on a JPG by setting it on a background identical
to the background color on a Web page.)
- Optimize your graphics for small file sizes.
Your entire Web page should load in about 8 seconds at 56k. Full-featured
image editing programs (such as Adobe® Photoshop®) provide
tools
for image optimization. These include reducing the color palette,
creating slices, and increasing image compression. Be careful
that your selections for image optimization do not degrade image
viewing quality.
- Always use "alt tags" for images,
as a component of accessibility.
- All IU Kokomo logos, wordmarks, and symbols are trademarked
and copyrighted
by Indiana University . Further information and regulations governing their use
are here.
Image dimensions and proportions (size)
Do not resize images in browsers;
this degrades image viewing quality. Resize your images in an image
editing program such as Photoshop, then specify each image
size at its actual pixel dimensions (width and height)
for the browser.
Each image should be presented at 100 percent
of its original proportions. Do not stretch or
squish images to fit a particular area of your Web pages.
If you need an image at different proportions than your original
image, either crop the image to fit the space at 100 percent proportions,
or select an alternative image that better fits your Web page.
In addition to using 100 percent dimensions and proportions
for your images, please make sure that your images are prepared
at 72 dpi in your image editing program. Browsers
have to "interpret" images at other sizes, and the results
are undesirable.
Finally, larger images are not necessarily
betterin fact, they often distract from the professionalism and
usability of your site. Remember that people use browsers of different
sizes, so a 4x6 image on your browser may take up most of someone
else's screen.
Getting help & using the IU Kokomo image gallery
If you do not have experience with creating
and editing images for the Web, we recommend that you obtain assistance
from someone who does. You may also consider attending one of the
CTLA workshops on this topic
or contact the
Office
of Communications and Marketing.
In addition,
IU Kokomo does provide a
gallery
of images online for official Web development at IU Kokomo. These
images may or may not suit your needs; we will be adding images
to this gallery over time. PLEASE NOTE that all images in the
gallery are permitted for use on
official
IU Kokomo Web sites only.
