My Mediagoblin instance with better image quality & EXIF data

In my continuous attempts to free myself from proprietary webservices and run my own Free Network Services, I’ve finally set up my own GNU Mediagoblin instance. This is a multimedia gallery project to host, show and share several kinds of media files, like images, videos, ascii art, SVGs and even 3D models. From the Mediagoblin site it describes the project as:

MediaGoblin is a free software media publishing platform that anyone can run. You can think of it as a decentralized alternative to Flickr, YouTube, SoundCloud, etc.

One thing I noticed was that the quality of the images was not good. I enhanced the quality of the image resizes done by default and the improvement was noticeable. It’s still not as sharp as Flickr’s quality yet (I don’t know how they do it) but it is cleaner and with no artifacts.

Also I’ve enhanced the way the EXIF info is presented. I added a camera settings section that shows key relevant info most photographers are interested in looking at: what camera was used, when the photo was taken, exposure, aperture, ISO and focal length. By clicking the “Additional Information” button you can now see all the EXIF information on the file that was previously being omitted.

I hope my patches get accepted upstream and I plan to continue working on the project as I find it very useful. The planned features for future releases I’m eagerly waiting for are the API and the multiple file upload. That way I can post more of my content easily and maybe write a script to import all photos from Flickr. That would be nice.
