Photo Organizer

I've wanted a slideshow mode for some time now, but is one nasty technical limitation -- there's no guarantee that the "hi-res original" is viewable in a browser (jpeg, gif, png only). This is particulary true for RAW images, and generating full-res jpegs from the RAW images is a feature I personally need. (see #7)

The other limitation is that the originals these days greatly exceed screen resolution and the file sizes are pretty big -- you want to reduce the image size (for bandwidth reasons), and not serve an image larger than what the browser wants (browsers suck at rescaling. :))

The proper solution here is to add more auto-generated image sizes, and then the slideshow code would use one of those sets.

Then there are the obvious permission problems, but I'll avoid that by making slideshows initially for photo owners.

For the image part of the problem I could imagine to use a third-party tool; I use for that the image viewer 'gqview' (http://gqview.sourceforge.net): I generate an auxiliary directory containing the links to the images to be shown and start gqview from the command line.

If you're going to go so far as to require external tools, then this sort of a sliedshow could happen via the already-existing export mechanism.

FWIW gqview doesn't handle RAW images directly (though its development branch handles extraction of embedded JPEGs), which isn't the same.

Using the export feature means:
Retrieve the tar-file
store it to some place
generate a temporary directory
untar the tar-file
invoke the image viewer.
This seems to me to be a bit lengthy procedure.
What I imagine is to have a button 'show', which stores the links to the selected files in a temporary directory and invokes the image viewer.
The string to invoke the image viewer could be deposited in the config_site.php; this would by the way delegate the responsibility for the
image viewer to the user.
