Good to re-size any photos if at all possible to 800x600 - or less (640x480 is usually plenty big). This really speeds up loading images (for those of us who sometimes get stuck using slower browsers), and is also simply convenient for viewing on the screen in the bikeforums. If you use a free web photo-hosting site as Charles Wahl mentioned, you can usually select different image sizes... click on the one best suited... then check that published images "properties" to copy the URL for that specific image and size... then you can either just post the URL or bracket the URL address between a simple [IMG]...[/IMG] format to show your photo at that image size in your Forums post.
