If your a live journal user then your most likely to be more of an expert than many site owners when it comes to the uses of an 100x100 icon. But most commonly 100x100 Icons are used for blogs and forums. They can also been seen for showing what you like most, more like a small picture show case.
100x150 Icons
Not sure how many icons are going around in this size, but I made them mostly for my website and Myspace DIV layouts. Its was more of an added extra thus the collection being so small. They can be used for any profile you may own that allows HTML, or you can just add them wherever you please, your blog, your profile, or personal site.
50x50 Icons
Otherwise known as AIM icons, so obviously you used them for AIM, but if you want they can also be used for your profile, my collection is very small due to them being used for my fanlistings so if your a fan of whatever is on my icons you can check it out here.
If you want to add more or clarify my uses listed above by all means send me an email at Blaqheartedstar[@]aol.com
