Automatic zip extraction

[bhafer]

I've seen a bunch of other gallery softwares that will automatically extract zip files with all the images in them into the database.  I know this is not a feature with this software, which is the best around.  My question is if anyone knows how to make this happen.  I would really love to have this feature, and I simply can't wait until 4homepages adds it to a later feature.  Any help would be greatly appreciated!

Regards,
Ben

Gallery does it as well - http://gallery.sourceforge.net/

Great Idea!
Look at my thread:
http://www.4homepages.de/forum/viewtopic.php?t=3946

PLEASE, can somebody write a MOD?

Thanks a lot!

I believe, it doesn't make much sense to zip one image only - jpeg images are already good packed. So, this should be implemented together with multiple images upload only.

[bhafer]

I agree.  This could be used for one images (doubtful) or for multiple images.  Currently other gallery softwares allow for registered users to upload all their images from one zip file, and it will publish the lot.  This way they don't have to upload one at a time.

I understand part of the problem because the software allows for a title, key words, description, etc.  But I would think you could use one for the entire upload, and then the user could go back to modify their entries per image if they choose.

I'd have to imagine this would be easily accomplished from someone who understands php well, which I don't . . . not at that level.  I have talked to programmers who have implemented this type of solution, and they seemed to think it was pretty straight forward.  There only grey area was on the software itself, and actually implementing the solution to work.

Has anyone created a Mod to allow for this kind of feature?  Additionally, is there anything in a near future release that would have this available?

Thanks again,
Ben
