I'm trying to copy images from one album to another, but as it seems I don't quite understand the way Gallery does such things. As for now there seems to be no module that has implemented copying images. Or does anyone know a module that already has this functionality?

What I want is pretty simple: I've got a list of image-ids and want to copy them physically to another album. There has to be no connection to the original.

Can anyone give me a hint how to do this? Any code I can look up as a reference how Gallery creates images? Thank you in advance.

There is no module to do this in G3. G2 has this feature if such a feature is that important.

Ok, I'm as far as being able to copy images. Here is what I do: http://pastebin.com/nPtnr6vr

But I've got a problem I couldn't figure out yet. For some of the copied pictures the system is not able to retrieve a thumb_width and thumb_height. Because of this $child->has_thumb(); in the view which displays the images fails and the thumbnails are missing. The images itself work just fine.

I couldn't figure out where these fields are set. Where do these fields come from? How can I check, why they are not set for some of the images (because for some they are and the thumbnails are shown).

Has no one ever worked on how the system fetches the information about thumb_width and thumb_height? Because I couldn't find
a solution until now. If anyone has any idea, a little hint, I would be really graceful. Thanks.

Thinking of a possible workaround, maybe it would be a good idea to set the dirty flag for the thumbnail in your copy process before your final save. I may be looking in the wrong place, but take a look at modules/gallery/models/item.php in the __construct function and see what it does when creating a new item.

Thanks for the hint, but sadly it didn't work. What worked was setting the thumb_with, thumb_heigt, resize_with, resize_height manually.

My module is more or less a dirty hack, but as soon as it's ready to be deployed I will publish it.

Not sure where you're running into difficulty. The pastebin code doesn't include any reference to the thumb dimensions; did I overlook it?

You've tried using $item->thumb_width and $item->thumb_height?

Worst case, the info is also stored in the db items table and would be accessible with a db query.

Note sure what you've tried and what file you tried it in, but hope that helps.
