"Full info" doesn't give full info, image size tiny, no buy button

Issue Summary

I've installed this module on a client's site, and have run into several issues:

1. The "Small image and full info" option under Display Fields doesn't give very much info at all - just the very basics (title, author, publisher, binding). It doesn't even have price, let alone a description or anything else useful.

2. The image isn't just small, it's practically microscopic - there's really no point in having an image at all if it's so small you can't make out any detail at all. And while choosing the "large image" option gives you an image that's slightly less tiny (though still really too small to be very useful), it leaves you with absolutely no information at all, not even the title. Isn't there some way to have a decent-sized image, or at least have the slightly-less-tiny image with some actual information?

3. There doesn't seem to be any way to add a "Buy now" button or anything like that. At first I thought it actually didn't link back to Amazon at all, which confused me since the configuration page asks for your associate ID, but eventually I realized that the title was a link. This really isn't very user-friendly - I can't see visitors to the site bothering to mouse over everything just to see if there's a hidden link somewhere. If you want them to buy something, there really needs to be a clear and visible way for them to do that. Does anyone know if there's some way to add an actual buy button?

The test page seems to retrieve a lot more info than the "full" info the CCK field does, but there doesn't seem to be any way to actually display any of it. The only means I could see in the documentation of accessing any of it was with the filter codes, but that's obviously not ideal - it it looks like they're intended to be inserted in the body of a node, and that seems like a really awkward and inefficient way to build a page. I want my client to be able to maintain the site herself, but she's not going to be able to do that if she has to type some special combination of arcane codes in on every page - that's the sort of thing using a CMS is intended to avoid! Unless maybe there's some way of building them into the template for that content type?

Similarly, I could probably add a Buy Now button by copying in the HTML for it as part of the body of the node, but again, that kind of defeats the point of using a CMS, and means the client probably won't be able to do it for herself.

Isn't there some way I can set up the site for her so that she can enter a book's ASIN and get an actually useful page out of it, with a reasonable amount of info and a buy button that users will actually recognize?
