Hi there, and welcome to the board. We have a techie tip for posting pictures
here. There are instructions for using Irfanview to reduce the size of your pictures. Use resize/resample to do this, rather than saving the file with less resolution, as you'll lose detail.
If you like, you can forward the photographs to me. To get my email address, just click the little envelope under my username in the info block to the left of this box.
