Doesn't work with Optimize CSS feature

Using Drupal 6.9. When the Optimize CSS features of Drupal is enabled, it breaks the images used in this theme (notably the rounded corners and gradient backgrounds of the header and footer sections as well as the page background). This is because the optimized CSS will look for the theme images in this location:
/sites/all/themes/images/salamander1/
When in fact the theme has them stored in this location:
/sites/all/themes/salamander/images/salamander1/

I have no clue how the Optimize CSS feature creates the combined CSS, but can something be done with this theme so it still works correctly using Optimize CSS? I get around this by creating a symbolic link.

Thanks.
