i get a 404 error whenever I upload an image. It then points to mysite.com/image/z while I think it should rather point to mysite.com/images/imagename.jpg
Make sure that mod_rewrite is enabled. If mod rewrite is enabled try to edit Chevereto's root .htaccess and remove the "#" before "Rewrite Base /". If nothing works then ask your hosting provider telling them that you need mod_rewrite in your website.
