Thanks horselover360 for the nice comment on my pic. I had a nose on your profile and saw this and thought i'd reply as no-one else had!
You need a photobucket account which is free and easy to set up. http://photobucket.com/
Upload your pics onto photobucket, once you have done this click on the picture you want to use then you'll see a link saying share, then click on get link code, then select this option: IMG for bulletin boards & forums (i always choose full size version).
Copy and paste the link code onto your forum post, et voila!
Hope that makes sense. I'm sure there is a post by admin explaining it, and probably better than me!
Look forward to seeing some of your pics, what do you have?
