poetter

I worked something out, that saved me a lot of time.

I copied the tabs Create new gallery and import Image folders, replaced the text input with a textarea, so you can place a comma separated list. While processing i exploded the textarea input and surrounded the worker call with a foreach.

Create multiple galleries works like a charm with my 78 galleries, though there will be a limit by php_execution time. Import Multiple folder has got the same limitation and i tried it with stacks of 25 galleries. For some of them there were no thumbs created, but that is a task you can do from the gallery overview.

So creating the galleries, copying files and importing them took me just an hour. Creating thumbs took an other hour, but that was a low brainer.

My mods are quick and dirty, need some style clean up, but they work.

Here is a diff of the modification to the original file

Hi there and thx to Alex for this great plugin.

I also have to import about 100 galleries with over 2000 pictures.

@chuckrock, alexrabe

Did you work something out you could share?
