Ushahidi should not upsize uploaded images, only downsize them.

When you upload an image with a report, it is forcibly resized to fit Ushahidi's large/medium/thumb formats. However this means that small images are **upsized** to fit these dimensions. 

I am not sure if this is intentional, but it results in a lossy, pixelated image being saved, and it would be much better from a user experience perspective to just save and display the original image instead.
