What a mess, you're right. I have noticed that the MSN reads the ISF part, if the user have Journal Viewer. Now, we have to discover how the ISF are made... One thing we can observe is that ISF format needs less space to represent the GIF. Now I enumerate things we can supose about ISF format:
- The GIF it's independent from the ISF. The gif can be completely different from ISF, but MSN with Journal Viewer only looks at ISF. - The ISF needs MUCH less space than GIF. That is possible probably due to ISF it is more limited than GIF (i.e. palette colors?). The compression algorithm should be more simple... I think.. - ... More ideas? Anyone familiarized in image formats? Cheers, Cristian.
