Your best to upload your picture to a free Photobucket account, then copy and paste the IMG code in your thread. Photobucket will take care of the size.
We request that pictures be no bigger than 800x600... Otherwise they end up being too big, and people have to scroll the screen across. Please resize the pictures to 800x600 before posting links here... Thanks.....
Thanks guys. I tried the photo bucket and noticed that it changed the jpg files to a png. So I copied the png picture back to my computer, and it posted with no problems. I still haven't found how to make them that big though.
