One of the common problems is misunderstanding (or carelessness?) the difference between URL and Path.

URL - is something like http://domain.com/blabla/, i.e. the location of the file on the internet.

PATH - is the location of the file on disk.

Let's consider a simple example: on the server disk the directory with your domains is usually located something like /home/user/domain.com/. Let's say the file 1.html is also there. The path to it is /home/user/domain.com/1.html The URL to the same file is http://domain.com/1.html

Relative vs. absolute paths: - A relative path is relative to the current location and can change - An absolute path starts with `/` (file system root) and never changes. Example: `/home/user/domain.com/1.html`

In rotation settings: You specify two parameters for thumbnail storage: URL to data and PATH to data.

For example, instead of storing thumbs in `/scj/thumbs` (http://domain/scj/thumbs/1/2.jpg), you want them in `/thumbs` (http://domain/thumbs/1/2.jpg):

- PATH to save thumbs: `/home/user/domain.com/thumbs/` - URL: `http://domain.com/thumbs` or just `/thumbs`
