You have two options:
1. Invest some cash in a nice D-SLR, brush up on your photography skills, splash some more money on CF-cards, put time aside for photography. Practice, shoot, get your hands dirty with the digital workflow; RAW-conversion and what have we. Tweak and tweak, upload carefully tagged stuff to your Flickr-account.
2. Shoot something Mac-related with a cheap camphone and let the Mac-heads do their magic: TUAW and BYODKM.
Option #2 is hereby recommended. My latest shot didn’t make it to the top of my Most Polular-list, though. That special place is reserved for… A snapshot of my Powerbook…
Well, that didn’t last long. The Mac mini shot is now the most popular…and will probably continue to be for the duration of my time on Flickr…
