Hi.
I discovered an incredible program a while ago, which would be an enormous asset for IrfanView if integrated as-is (or at least some of its functions) into IV - either into the main program or into RIOT.
ImageAnalysis:
(1st link is original homepage, 2nd link is google translation, as the page is in Russian, but I assure you it's totaly worth the extra effort for non-russian speakers!)
The goal: to convert the image to the smallest file size possible while maintaining a minimum user-defined similarity percentage.
The concept: is really so simple and effective that I wonder why noone else has come up with this before: the program converts the image into .gif .png and .jpeg (in different quality levels for the latter), and chooses the smallest file that still matches a minimum similarity.
Judging from his other apps on his homepage, the author seems to be quite maths-savvy, so he seems to apply a sophisticated method to determine the similarity (color-similarity and luminosity-similarity).
procedure:
1) user opens file
2) (optional) user enters/changes minimum similarity percentage
3) user clicks on analyze
4) if satisfied user clicks on save (otherwise changes the parameters)
As simple as it can get !!
There's also a batch conversion mode to optimize all files on your harddisk if you wish!
Here are a few screenshots:
results of the analysis:

batch mode:
There are many options available. For example you can specify a minimum percentage of file size gain and if this gain is not reached, the original file is kept as is.
