the sizing thing isn't too hard you just have to take the picture down using your edit thing. Basically you right click on the picture and there is an edit tab, it should be set for 100x100 and you change the numbers to something like 50x50 or 25x25 depending on how long it takes to get it down to what this site will handle.
Turner and hootch is exactly right. He's a French mastiff or the correct name is Dogue De Bordeaux. We picked him u p from an out of state breeder for about 2500.00 He's real intimidating but in all hostly he will lick you to death lol.
