Hello,
if i'm not wrong, the plugin doesn't look for password at galleries, and also it don't consider access permissions (everyone, only members etc.), so it will shows any thumbnail of images own by a user.

I think it could be fixed easy into sql query putting the exclusion for galleries with restrictions or with password set.

Could this be considered an accepted feature request ?

Same request here. The plugin shows thumbs from restricted galleries. Please try to fix that.

Better would be that Zoom finally gets a good system to control the access to galleries, i guess then it would be easier to integrate, but for this I am already waiting for several years.......
