Is there a way to peruse a list of SteamID icons to choose from?

like websites that list the most expensive inventories or highest steam levels? not really.

No, just like a list of SteamID icons that can be used in plugins like this to get their icons.

No. It's not like workshop items. It just uses the profile pic of a steam account. You can make a free account and upload any picture you'd like.

Yeah, I know.  Was just wondering if someone had a list of collected ones.  Thanks!

Most common use is likely server owners using their server banner as the image
