Create animated GIF's with C#

I got a brand new camera this christmas, a GoPro Hero3+. The camera shoots amazing Full HD video at action-enabling framerates. And the waterproof casing and small form factor makes this the best damned piece of gear i own.

And after spending hours on hours of tumbling in the snow videoing myself fighting with the dog and jumping off cliffs skiing i started exploring the various other functions the camera has.

One of wich is the ability to take 30 pictures in 3 seconds.
Combined with a handy wifi-remote makes for alot of fun shots.

Then after having 500+ still frames of action recorded on the SD card i realized it would be fun making animated GIF's with them. A quick google search gave me lots of online-sites for just this purpose, but the first one i tried gave me a "picture too large" -error.

And being  the programmer i am, and having a few hours of post-christmas tranquility i immediately decided that i would rather make my own GIF-converter than manually resize my images to fit the online-converter.

Granted, the next few search results would probably solved my problem, but im allways trying to keep my coding skills from decay, and this presented it self as a good opurtunity.

So here is the result of a couple hours of dabbeling i Visual Studio:
The VisualStudio project can be downloaded as a .zip from this link

And a .gif example:

For some reason the gif will not loop, but im working on a fix for that.
