Touchup is an image processing applet for displaying GIF and JPEG images on a web page.
It's a powerful, interactive replacement for the
HTML <IMG> tag.
By clicking on the first button that appears when mousing over an image,
visitors can easily adjust images to their computer and viewing conditions.
For example, increasing the gamma in one image will make all images in a gallery appear brighter.
and even for each visit through the use of
Click on the magnifying glass to zoom in on an image,
click on "i" to view EXIF and IPTC picture details. Note: all images on this page are non-working screen snapshots.
