Thanks SD....with BOAC's help I think I've got all that set up about right...the problem I now have is within Photobucket, in that when I'm resizing downwards to suit pprune, sometimes it files the image in the new size, and sometimes the image just reverts to the original size. I'm sure it's a simple piece of finger trouble, but I cannot see where I'm going wrong.
BTW, of the options offered by Photobucket, which is suitable for pprune?
