I also change my desktop photo regularly.
The previous one I had was very similar to my current one, it was the same aircraft, just a bit closer to the terminal so that you could see the doors from the airbridges. I have also had several VLM Fokker 50s, my old horse Stjarna, a Dash 8 Q400 of Augsburg (chosen because the first Q400 I saw was an Augsburg example at LCY) and sometimes I have selected set ones which were supplied with XP, such as a nice one of Stonehenge which I had for a while.
When I was at college, I was always changing the desktop, and had a Sabena A321, a view of Brugge taken by VC10 (which is on my Belgium Photos site), various VLM Fokker 50s and the Atomium. Then they made a rule at college to say that no more "personal" desktops were allowed and we could only have the standard college logo after that (which, believe me, was bloody hideous and not as nice as the ones I have mentioned

)
I am, however, always on the lookout for new desktop photos

Sabena and Sobelair - gone but never forgotten.
