Fuzzy Thumbnails (not a re-size)

The thumbnails on my site are showing up fuzzy. I have been uploading six photos per item and have not had a problem with the correct image showing up as the thumnail. They are sized correctly from the beginning (150x112). But once I upload them, the thumbnail looks terrible. I am not sure how to fix this or what I am doing wrong. All the other pictures show up correctly. I have viewed this in Explorer. I have tried to install IH2 and I messed that up so I am find with going the long way with these pictures, and I am sure I am uploading them correctly.

Here is the page in question.

Disregard this post, I got this worked out, I had set the size slightly different in the admin that it actually was, hence the slightly warped images.
