Poor image quality

I have run into something weird. I am working on a photography site that was created in flash 6. I am making updates to the site with flash 8. The site has a main swf file and each section has its own separate swf file. I made some updates to the main swf file only and exported it out as flash 8. Now all the images in the other swf files are all blurry even though i have not made any changes to those files.

Does anyone have any suggestions as to why this would occur?
