Theres no dump people here, just people with alot of answers.
Easiest way I try to upload a picture on a thread is cutting pasting it in Paint, then saving it on your desktop and a JPEG file.
Then if you look under the Submit reply button before you post a response under Additional options, click on Manage Attachments, from there look for your picture on your desktop then click add, once you submit your picture will be uploaded, after that just delete the picture from your desktop.
