When making a reply like I am now or starting a new topic below & to the left of the text screen is Additional Options... click there & a box will open for you to browse your computer to select the pic. you want to upload. For more than one pic. click (more attachments) to the right of the Browse button. Allowed file types: jpg, gif Maximum attachment size allowed: 300 KB, per post: 10
Most pictures have to be resized, I open them in MS PAINT & under tools use the stretch/skew selection & enter 50/50 till the pic. fits inside the window & then save as .jpg.
