[closed] How shall photo galleries be presented at Dikutal?

We in Dikutal are on the lookout for a better way presenting and organizing our galleries. Currently we use a Drupal module, which isn't very nice at presenting the images and which is even more horrible to work with if you want to upload and write comments for those images.

Two years ago i hacked together a very simple gallery for my lunch club "EggsML", it hasn't been used very much, but I find certain parts of the approach nice. A gallery is directory named with the title of the gallery, each gallery-directory contains collection of .jpegs and any other information is saved in the EXIF data of that jpeg. See the code here: https://github.com/Athas/EggsML/blob/master/jpeggs.aspeggs (.aspeggs is just a pun on .aspx, but it really is a Python file. Also, our .jpeg files are named jpeggs). The gallery generated by the above is viewable here: http://eggsml.dk/jpeggs.aspeggs

This is mostly a prototype, a lot of desirable things are missing (comments, user authentication, and upload mechanism, changing EXIF comments through the webinterface etc.)

Does there exist any good gallery web-apps that we should consider to use instead of creating our own hack?

Edit: I think we will prefer an on-premise solution. That is, we don't want to embed Flickr, Picasa og SmugMug galleries. There is always limitations on such services, and it is just nicer to use something Open Source which we can adjust as we want.
