If you don't mind spending a little bit of money you can phone the USPS and set yourself up a customer account.
You can then buy a sheet of Global Forever stamps which they will send to you.
1 stamp should be enough to cover 1 photo.
You can also work out the weight of the return envelope. Do a postage rate check on USPS website and then put the relevant amount of global stamps on to make up the value. They are approx $1.10 a stamp.
Sheet of 20 cost about $28 inc postage to UK.
I buy 2 sheets at a time costing about £25 in total and then just use them when I need them.

Unfortunately you have to phone them though as the USPS website does not do international shipping of stamps but they are pretty clued up at customer services.
Also a cheep way to phone is put a couple pound on a skype account and use skype. Costs me about 15p a phone call.
As a side.
The canadian postal service also do international stamps which you can order online to be shipped to the UK.
But be aware they ship by surface mail so it takes approx 6 weeks as it comes over on the boat.
Hope that helps.
