Ray, how to upload images (see pics). Firstly, don't use the quick reply box, rather press the "add reply" button on the lower left of the page. Once you do that, scroll down until you see the "manage attachments" button. Pressing that brings up another box where you can upload images from your hard drive using the "browse" button. Then you press the "upload" button and Bob's your aunty, you've uploaded an image.
I think the forum has an auto resize feature, but a good little program if you don't have it already is IRFANVIEW. It's free to download and is easy to use. Good for images of anything from Aunty Jack, stars or the cat.
If you are having trouble just yell.
