Picture Quality wih the "XML Photo Gallery" tutorial... Help!

Hi, I’m new here, so I aplogize if this has been covered.

I used the XML Photo gallery tutorial (http://www.kirupa.com/developer/mx2004/xml_flash_photogallery.htm) and found it to be brilliant and helpful. My only concern is that the image quality seems to be lacking.
They look fuzzy in each picture. I’ve even played with the publish settings, and made jpeg quality at 99%, and is still comes out looking like a much lower quality version of my original jpeg when I view the HTML preview.

If you want me to post anything, let me know, I was hoping maybe someone would have a quick answer!
