About 4 years ago I stopped using good 'ol film cameras and went fully digital. I've been thinking for a while what to do with the digital photos long term. Technology changes quickly and in the space of a couple of decades my photo collection could be effectively lost to future generations.
Long term the only viable solution is probably to print out the photos onto decent quality photo paper.
Short term I have been considering buying some digital photo frames, loading them up with photos and sending them to family members - until I found out some hackers have managed to load viruses onto photo frames that are sold in large US chain stores.
