In this set, my results are similar to the last; the file's original format was much better suited than the other formats it was resized into. The only difference was that the original file format was in jpg, specifically progressive jpg. 

No matter how it was resized, the reformatted pictures lost quality merely because they couldnt handle the precise detail, or colour gradients. For instance, the gif formats gave the picture unnecessary noise while bmp formats saturated and thickened the sky gradients.
