there should be 3 "links" under the pic, they all do the same thing but for different sites. if you want a link to be clicked on and open a new window, you copy and paste the one that starts
http://www....., if you want to post a picture without a link that is visible in the thread, you copy and paste the one that has at the beginning and end. the other with < > marks is used for sites like myspace, etc. and no, 500x500 isnt small, its decently large actaully, avatars are usually 100x100 max (varies with sites). I hope this explains it, any other questions? test a pic out!!!
