A few nice photo edit online images I found:
London

Quite different from the Gherkin shots of late :)
This is a crop from an old photo which wasn't very high resolution in the first place (the Lumix FZ7 had about 6Mp which was high at the time but is now the domain of cheaper phones). It was then resized for the exact pixel size to serve as a background for an Android phone (the Sony Xperia screen plus extra width for sliding sideways for more windows). Colours and detail were boosted to highlight the vibrancy of the small screen. Despite the resolution degradation, it's still viewable on PC screens (except the largest ones, where imperfections start showing).
The purpose I brought it up was for a 'Before and After' comparison assessing the capabilities of online editor iPiccy (see links below).
