Thanks very much for the e-mail Des. I found an icon on my desktop - it's a fairly new computer and I am still getting used to it - named Snapfish, and it seems to do the same thing. I will investigate the other web hosting services at some time, but I will see if Snapfish does the job. As with most images I find on the internet I often obtain multiple copies. The reason for this is that occasionally it is possible to obtain a better, sharper copy, or perhaps even though the photos look identical they could be slightly different to each other. I have uploaded two versions of the photo I had in mind. They seem to be the same photo, although the colour is slightly different, and they have been framed slightly differently to each other.
Edit - 1st September 2013. I've just realised that I posted this reply in another thread!

Oooops! Anyway, I hope the photo is of interest to some members here. I was certainly impressed with the quality of the photo and the subject shown in it. There are many such photos for sale on eBay on a regular basis, as well as other sites I am sure. It's a lot of work to look for them though, and when buying such photos the cost certainly adds up quite quickly if you're not careful.
Thank you very much for the advice about file compression James. I am surprised that digital images can be cleaned up. It sounds like a bit of an art, and worth having a look at some time.
Regards,
David.
