Okay, going to throw in my suggestions.
Put [???] tags around every icon to signify who owns them, so like this:
[???="Made by Abnegation"]
[/???]
I think that members should be allowed to post as many icons as they like -possibly- but they should all be different. Meaning that they can't post more than one icon from the same sort of stock or similar style. So I think Galuxxy, you should repost with just the one.
Furthermore, I think that the wall should only host icons which are open to the public, meaning that any member should be allowed use them provided that they give credit to the user who made them, I think it could be a neat little resource and a nice way to get members more recognition for their work.
But, Gazza, you have the final say. Let me know what you think. Great idea buddy! Oh, also mark me down as a maker and throw that icon above in the wall too. Contact me if you have any further queries or ask in the Lounge~
Thanks for the suggestions I'll definitely use the [???] Tags and allow people to add as many images as they like well because three just isn't enough. :>
As for the suggestion about making the icons public it can vary from user to user depending on what they want.
So the the icons will look a little something like this: [???=Made by Gazza. Public: Yes/No]

[/???]
Also I was wondering if the thread becomes popular could you hand out emblems to members who contribute a certain amount of icons to the wall?
