Indeed, 900 x 572 is very low, it
cant be printed with quality. In the other hand, 300dpi will be way too
large a file.
What you need to do is get a larger file that is
manageable in gimp and other tools.
You can try to photograph again
with a better camera (more mpixels) or use a panorama tool to stitch
partial images together.
There is this nice tool called Hugin
(hugin.sourceforge.net) that can do this for you. It takes a little
getting used to, but no big deal. I managed to get a 110mpixels image
