Using large images on iphone

Hi everyone,

Was wondering if anyone knows of a way of copying full resolution images onto the iphone? I wanted to copy a London tube map onto it at a 3k resolution but when i copy it over using itunes it scales it down and is such a low resolution that you can't read the station names.

Thanks in advance!
Simon

Email it to yourself or save a copy using safari and the tube's website. (Tap and hold an image to save it).
