Mail not displaying some images properly

Hi guys, I've been having a strange problem with Mail in Lion lately. Every day I receive Favorite Searches emails from eBay - about 50 or 60 of them. They are formatted to have thumbnail images of each search result. Some of them display like this, which is proper:



While others display like this:



Doesn't seem to be a pattern to it, either. One email won't show up right, but the very next one in the list will be fine. Then the next one will be bad, etc. I've made sure the "display external images" option is selected.

Any other ideas? Thanks!!

 

Well, that's what I thought, too. So I looked at the emails in Gmail in Safari, and all the emails/images show up perfectly fine. So I don't think it's anything wrong on eBay's end. It's something that's happening in Mail when it renders the emails.

 

Well, when I use Gmail's web-based access in Safari, it loads every one of these emails perfectly - images and all. Why is Mail displaying half of that same bunch of emails improperly?

In other words, if Gmail's web-based platform loads the emails correctly with full images, that means the problem isn't with the emails' formatting, right?
