Photo hosting script, any recommendations?

[versa]

Anyone have recommendations for a good photo hosting script similar to imgur, etc? The script should be open-source, efficiently programmed and actively maintained.

Some of the things I would like to do would be;
. import photos by FTP, ZIP. Import recognizes directory name as title for the gallery and creates unique galleries
. interface to import multiple images by URL (ideally a scraper as well) and from computer
. organize photos by gallery
. generates thumb and intermediate size pic (size controlled by admin)
. generates embed codes (BB in particular) for entire gallery and as well as for individual pics. Embed codes should link back to full size pic gallery (need to insert ads around full size pic) and the IMG= which will show on the external site should link to the intermediate pic (not the full size one) to save some bandwidth on my server

Ideally would have a good user interface like imgur, etc so in future could promote for user use, initially will only have a few people using.

Had a glance at http://imagenuke.com/, http://imagetize.com, http://www.image-host-script.com/ as well as Coppermine but really have no idea if these are any good or not.

The requirement to have a one-button generation of embed codes for the entire gallery does not seem to be a feature with any of them so assume will need this programmed.

Thanks!
