Is there any way to have minishowcase update automatically the galleries, based on the contents of each folder? I mean, if I delete one photo from one folder it would be great that it would also dissapear from the gallery for that folder. Is there any way to do that? Thanks!
if you delete the thumbnails for that gallery, they'll be recreated and the image will disappear. look for the thumbnails in the /cache/cache_[gallery_name]
unfortunately giving minishowcase the ability to delete files might create a possible vulnerability that could lead into a possible security issue.
