I get this message when I hit that link you posted :
You must be a registered user to view images!
You can post images right from your computer . I usually just hit the preview button below the quick reply box . Then click Additional Options . Then the Browse button .
If you can size your pics to 640x480 , they will fit nicely within this or most other forum formats .
You can also use a hosting service like Photobucket and have them re-size all your pics at upload .
