X3Photo Gallery Forums

There is no need to clear it manually ... X3 detects based on modification dates what templates and pages need to be recreated ... You can force-refresh cache by deleting the content, but I can't see any benefits of that. Furthermore, the resized images cache is quite valuable and doesn't doesn't really relate to changes in pages.

If you change URL, meaning you are changing the physical path to the image, then likely X3 will need to re-create and cache a new version of the image. It doesn't mean you need to delete your entire image cache though ... That means it will also need to re-create images from all the folders that are unchanged, which is an "expensive" process for your server. Worst case scenario, you will have some unused orphan images in your cache folder.

Thus, X3 will always get the correct image, or create a new cached version, regardless of if you delete the image cache or not.
