You don't have to use photobucket. DaytonaTurbo's guide to posting pics:

1)Type up your post, whatever you want to say.
2)Scroll down to hit the 'continue' button, make sure the box that says 'I want to preview my post and/or attach a file' has a checkmark beside it, then click 'continue'.
3)On the page that comes next, hit the browse button.
4)Find your pic on your computer. Click OK and submit your post.
5)If it kicks you out because your file size is too big, resize the pic using microsoft paint, then try posting the pic again. Resizing instructions here:
