From Idea Digital Imaging:
If you use Mail or Text Edit then you've probably had to resort to using an application like Adobe Photoshop or GraphicConverter to resize images that were too big or too small.
ResizeImage will scale an image quickly and then place it on the Clipboard so that you can simply paste the resized version straight into your document.
What's new in this version:
Added a routine to stop errors when ResizeImage cannot determine the colour space of the original.
