yes i know there is lot of other topics similar to that , but i like this site more because it gives you the direct link to use in forums , i used other sites like imgur but you need to search for the proper link of the image and sometimes its sucks for me , i hope you got it
I wanna notify you that imgur also provide direct bbcode forum links for every image and you can crop your image there if its necessary.
