I can't help with Photbucket, but to get it to 2mb, reduce the picture size in Microsoft Word or Paint or something. I know there are online sites to reduce pictures, too, but I can't think of one off the top of my head.
The Revell box art has turned me off of buying a kit before.
Whoever built the model couldn't paint the window seals in a straight line, tail lights painted half-a$$ed...
I'm glad that we bought all of our rolling stock kits when we did.
We bought probably fifty kits, mostly Bowser ones, for about $5 a piece when they were on sale.
