Whenver you publish a post or page or galelry, or save in the Visual Editor, the Gallery+ image cache should refresh.
Soemtimes though, when you make changes to a gallery, those changes may not be reflected on the site. To ensure they are, run the Refresh Image Cache tool if your old images are still being used.
Please note: Refreshing the cache causes no problems other than the next person who visits your site may have to wait a little longer as the cache images get recreated. No images in any gallery will be affected.
Click the button to refresh the Gallery+ image cache.
A messag will appear after the cach is cleared.
