Never occurred to me that the SEO module might be the issue, but I did suspect that the Product title MIGHT be the source of the issue. Though you did not have the exact same issue my client did, I do know that the product title will sometime affect how images are displayed... No matter... Glad you got it all worked out now..

So when using ultimate seo urls and image handler together, avoid using a C, P, M, PI, PR, PRI, EZP in the product title. Each of those are used in the url rewrite for creating specific urls for zen cart pages.
