Two months ago I had to organize some photos from my USA trip. I also wanted to make a presentation to show to my family and friends.

I use F-Spot to organize my images and since F-Spot has a very nice addin interface, I have created two addins for it to help me with my tasks:

• TimeShift - Shift timestamps of selected photos. Use-case: one travels to some country with a different time zone but forgets to change the time on ones camera. With this extension this can be done after the pictures are uploaded to the F-Spot.
• HTML Presentation - Exports selected images to a portable HTML/JavaScript based presentation. There are some existing addins that generate a HTML web gallery, which is not what I was looking for. The entire addin is currently at the level of a prototype, but I am willing to develop it further if there is some interest.

The addins can be found in my Mono Addins repository (not working at the moment ... sorry).
