is there any sites with just pictures of stuff not just cars, like anything, but good for drawing??

How can I post artwork on here? When I went to post a thread, it said that I can't post with an attachment.
Could you please help me?

you have to have a host, a good one is www.imageshack.us (http://www.imageshack.us/) and then you upload your picture. then, when you go to post it, copy the last link it gives you with just the URL, then in your thread type *then paste the URL*

example: YOUR URL HERE
