Using photo hosting sites.

[IDontKnow]

If you convert the photographs to sizes for email they shrink in size considerably.
Not sure what programs are out there to do it for you as I use the software for my camera (Olympus Viewer 3). You can convert a 3-4 meg picture to 250 to 500 k file with very little loss of quality. This is how I do it for our clubs website, saves space and time.

Hope this helps

PS There is a way to do it using your email program, bit long winded but it works.
Will write it up later and post it if people are interested
