Touchup - Features

Mini-control panel on demand. View example galleries 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. JavaScript can be used to keep these settings across an entire web site, and even for each visit through the use of cookies. 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. View examples.

Reduce Theft

Explorer 6 JPEG feature Protecting your work is difficult. With the HTML <img> tag a visitor can right-click on an image and take a copy. Explorer 6 even places a "save to disk" button (shown at left) on each JPEG image. Touchup defeats both of these features.
