Otto, You probably saved the images as RIFF (raster image file format) files, which is ImageStudio's own format -- if I remember right, that was just TIFF with LZW compression. Most Mac programs don't use any compression, or just PackBits (a simple RLE compression provided by the Mac Toolbox). If you can, I would just read them back into ImageStudio and save them out again (using the "Save As Other..." command) as TIFF files. I don't know of any other programs that read RIFF files.
