Big Pics are good
Of course I have cable modem. Beth and Robo do the "Click on the thumbnail image" which is great, time consuming but a real blessing for slower connections.
I like bigger pics though - they allow me to make wallpaper without TOO MUCH pixelation and if you use jpeg with 25% progressive compression - you take a 1024x768 pic from 1.2 megs down to 110K - without much noticable loss.
Don't ever stop the pics - there are larger beekeeping forums, but not too many of them have images embedded as is here - I like to think that being a very big plus in this forum, the fact that we can communicate in so many ways.
