Problems Galore Images and Pop Ups

I have managed to get the images working in cs cart.

Now the problem I have is this… I can’t delete the image, if I save changes the image is still there on the refresh in Admin and Shopfront? Help!?

If I click on the View larger image in the shopfront it gives me:

‘A file permissions error has occurred. Please check the permissions on the script and the directory it is in and try again.’ This is just on the pop up? Confused?

Can someone please be able to advise what is going on, its the latest version of cs cart and so far proving more hassle than good.

Thanks in advance
