Today I finished uploading all the photographs that have been sent to me so far. In the end I downloaded a program called JBatchIt which I used to compress all the photographs to a fraction of their size. The savings in space are about 20-30 times for each photo but with no loss of quality when it comes to looking at them on the web. I then used Picassa to upload everything to Google so they are now available for everyone to look at.
