Ok, so heres my problem:

I saved a google map for offline purposes as a jpeg, i used screengrab on firefox to do it. Its of amsterdam (5000x5000), and i can zoom from a view of the entire city down to the maximum zoom in preview to see the street names and whatnot. The problem is when i put the photo on my iphone and go to zoom in it just gets blurry and i cant zoom all the way to the street level let alone see anything else clearly...and fixes, please???

thanks

If you do this through iTunes, it makes a smaller version of the picture and puts that on your phone. Obviously that can't be zoomed very far.

Maybe there's a picture viewer in Cydia that can use bigger jpg's. Try iFile. And put the picture on your phone with DiskAid or something, so it isn't modified.
