It’s ok. I just went into the code and fixed it myself.
For anyone else having this problem, go into the CataBlog.class.php
find this bit of code…
// catalog item images
$values['main-image'] = '<img src="'.$values['image-thumbnails'].'" alt="" />';
change image-thumbnails to image-lightbox. That will give you access to the fullsize images bypassing the forced image resizer.
Now, you can size the image any which way you please on the front end.
