Icollator - a Java app to combine multiple Windows icons (.ico files). It's like Combine Icons, only better. What makes it better, you ask? Feature creep!
Like Combine Icons, Icollator lets you read in icons from multiple files and save the loaded images out into one humongozoid multi-image .ico file. This is useful if you have exported icons at various resolutions and bit depths from a standard imaging application (for instance, GraphicConverter, whose .ico export is unfortunately somewhat buggy, or Photoshop, via the nice free plugin available here). Unlike Combine Icons, Icollator is written in Java, which means you can run it on your Mac (for instance, to make a favicon.ico for your web site). Icollator also has nifty previews of the XOR and AND images that make up each icon within the file. Not particularly useful, but a fun programming exercise.
