Thanks for all the tips. I gave up asking my husband and managed to do it myself using Picasa (he was using some fancy pants programme which didn't do the job for some reason). Now successfully uploaded and should get the result in 10 working days. Without this forum my helper would be spending the best part of the day queuing at Immg tower.
My husband works in the IT sector but not on a helpdesk. He deals with high level strategies. Seemed like a good person to ask on a Sunday afternoon but glad I was able to turn to you guys to find out what I was trying to do wasn't impossible. PDLM, you may not be impressed by my husband's IT skills (I'm with you there in this case) but maybe you need to revise your knowledge of the IT sector, there is a huge breadth and depth of jobs within it, IT support is just a minor part of it.
