As the others said, use a photo editing/uploading site. Tinypic.com is probably the best site to choose when things like this happen. You need to go to tinypic.com and browse for the correct screenshot of the one you would like uploaded. Once done so, click 'UPLOAD NOW!' and you will need to verify something before you can continue. Once you have done so, wait until tinypic has done all its necessary things and copy the forum code [The second code from the top] and paste it on a thread/reply to get your image. :3
