IconView is the first Java applet that I wrote, and that's what it looks like, too. The applet is kind of a web browser plug-in that allows the viewing of PIC files (the Psion bitmap image file format, as used on the Psion Series 3 palmtops and other SIBO-based devices) directly in the browser. I thought it would be nice to be able to view PIC files before deciding whether or not to bother transferring them into a SIBO device.
Here are some images in the PIC format, downloaded from FTP
sites such as FrontierNet.
They may be viewed using the applet; the right kind of Java support is naturally required in order to do so.
Here's the source code for the icon viewer applet, in case you'd like to see it.
