I have hundreds of gigabytes of family photos on my hard disk at home.
What software will allow me to not only browse those online wherever I am, but most critically allow easy tagging via a web interface or app so that I can gradually organise the best of them as I view them, over the internet.
Update: Let's say I have a budget of GBP£300 for hardware/software, and I want the 400Gb of files kept on my home system so that I don't have to spend months uploading them. I tried that with flickr and it was quite time consuming.
Update: The Flickr interface fulfils all my criteria except the local storage part. I need image browsing software similar to flickr that I can run on my home computer and serve to the internet. With security.
