I have serious problems getting the cataloger run on my website. The cataloger isnt able to display thumbnails. I think the problem lays somewhere in Cataloger.Image.php and maybe my root url. I´ve been trying to solve this problem the whole day and Im getting really nervous now.
This is how it should look like in backend when you want to insert an image to a cataloger item (with "no-image" - image)

the "no-image" addresses to: modules/Cataloger/Cataloger.Image.php?i=products_ct_1_90_1.jpg&ac=624
and redirects to: modules/Cataloger/images/no-image.gif
And this is how it looks without getting the "no-image" loaded:

the address is also: modules/Cataloger/Cataloger.Image.php?i=_ct_1_90_1.jpg&ac=172
but it redirects me to an internal server error.
And of course the cataloger isnt able to create thumbnails for images i want to upload.
Im really going crazy with that problem. Maybe someone could please help me with that.
