I would hit the back button before either photo loaded and even if that were speeded up I would hate both of them. They are more about you than about the item, eventually you are not going to be allowed to have text on gallery pics anyway so why not get rid of them now, a discreet store name is one thing but yours just look like blatant self promotion.

The photo you have in the listing is a million times better than your ebay pic, I would take photos of that quality and use those.

I presume with the load time you are using hosted pics for the ebay one, only problem with that, aside from slow load, is if your hosting site goes down there are no pics. If you use a pic from your computer for at least the first pic then it will not only load quicker you have belt and braces.
