Amazon cover search: selection of cover resolution

I try to get the single cover of "Did I Say That" from Meat Loaf.

I get a query result and I click on preview. Than I'll see the cover.
This cover has a 240 x 240 resolution. If I take the cover and write it into the tag MP3tag tells me that the resoultion is 300x300 (in this case).

But if I click in the amazon preview I get sometimes covers with real 500x500 resolution.

Can I import both images the 300x300 and the 500x500?



Example from
in-grid with the title in-tango

the larger image has a real 500x500 resolution
