AHP,
I agree 100% with many sizes for icons and ask that as prontoedit.com is for all, send them up to be posted, or, if you like, download, resize, and send them back up. The icons on the site were a few:-) hours of my time scouring the web and then converting/resizing/entering in a database/zipping/etc etc. The site has no limits as to the numbers of icons. Essentially they are in 2 formats at the site, zips of the actual bmp files and either jpg's or gif's for display purposes.
SO,Send on the ICONS.
