I am in SOuth Africa and want to send some digital images to a printing 
service for delivery in London.

Prices I have seen range from 4p to 10p for a 6x4. Why such a big range?

Can you recommend one over the other (eg. pixdiscount, directfoto,photodeal 
etc.).

Images are about 3-4 MB from a Canon 350D. I want to send the smallest image 
size for a 6x4 print, by how much must I reduce the original image size?

Thanks

Joel
