I use Imageshack, it's free.
Go to imageshack.us and join
You upload pics and they set them in different formats for sharing or posting in forums.
Also, anypicture you see in the forum, right click on it and go to
properties that will show you what host they used. This one of our car will say imageshack.us/ in properties
If you use imageshack, when it gives all the different ways to post, use
Hotlink one for forums.(1)
One more thing,
use a photo program to resize your pics so they are not HUGE.
The above pic is 700 wide.
Good luck, let's see some pics!
