Advantages of IrfanView 32-bit over 64-bit version:
Runs on a 32-bit and 64-bit Windows
Loads all files/images for normal needs (max. RAM size is about 1.3 GB)
It needs less disc space
All PlugIns will work: not all PlugIns are ported (yet) to 64-bit (like OCR), and some 32-bit PlugIns must be still used in the 64-bit version, some with limitations (see the "Plugins32" folder)
