why can't u post pictures?
Right next to the 'Post' button on the lower right hand corner, is a button that says 'More Reply Options' click that and you get the reply box with more options. 'Attach Files' is right below the reply box. Below the 'Attach Files' label is a grey box and a button next to it called 'Browse'. Click the 'Browse' button and find the picture file you want to upload. When you select it is should now have the computer directory listed in that grey box. Now you must click the button that says 'Attach This File'.
The FAQ that is pinned on the main forum screen may do a better job of explaining and I attached a screen shot of what you need to be seeing when you attach the file.
Good luck I want to see your fix, must be exciting to re-fire with good results. Our re-fires hardly ever yield decent results.
