ok, what do you like better...
little black border....or... no little black border?misc models, photography Jessica Stam 
i think it depends on the picture. if its light like the second one i would use no border but it suits other icons really good :) you could aslo make a white border. may i use the second icon? i saw that photo today and LOVED it and now its a icon..i just want to use it :)
of course, be my guest! ♥ just remember to credit. :)
