I use "Resize" function in Fast Stone Image Viewer, together with some sharpening, which is the "standard operating procedure" when reducing the picture size.
Fast Stone allows for batch operations, meaning that I can select hundreds of pictures, and resize them all with one click (it does take time, but the process runs in the background). For that other site that I am contributing to (where I have 30,000+ photos uploaded, oh, the vanity!) I am going with 2272x... size, because it takes significantly less time to upload smaller photos.
Roy, please do upload your photos, I am sure there will be plenty interesting stuff for all to see!
Cheers
