go to Photobucket
and sign up for an account.
there you will be able to upload your images. When you do there is an option to resize them. Go with the 800x600 size as it makes them easier to view on the forums.
After you upload them and view your images, when you hover your cursor over the image it will display several codes for you to copy and paste. The one you want is the IMAGE code or [IMG]
- right click it, choose copy then paste it into your post here.
Takes a little practice, but once you hold your mouth right it's a piece of cake.
