I just updated to the latest IrfanView 4.20. http://www.irfanview.com/
It has several new features, the most interesting one being a 'Save for Web' option like Photoshop, PSP & Paint.NET. This seems to work very well & takes out all the guesswork when trying to save images at the highest possible quality while keeping within the forum file size limits. You can either adjust the output file size with the familiar quality slider or click the 'Compress to size' button & type in the desired size in Kb. It's a plugin so in order to use it you need to install the latest full plugin package posted here. http://www.irfanview.com/plugins.htm
This is the new UI from File/Save for Web.
