[AstroPy] Coding in Python to Read/Write a fits file.

I'm trying to focus on a part of the thread above ("Getting Started
...."), so that it isn't lost in that very long thread and is simpler to
deal with. It appears that, at least, one can use pyfits to read fits
files, and one can embed this code in a Python program. I posted the
coding aspects of doing this in a thread above, and finally someone
responded with code that looks like:
from matplotlib import pyplot as plt
image = pyfits.getdata('mpl51.fits')
fig = plt.figure()
ax = fig.add_subplot(111)
This is close to what I'm looking for. That is, executable Python code,
and not interactive code one enters line by line. Right now I'm lacking
a way to read, say, a jpg, fits, or gif file, and convert it to fits.
I'm also lacking a way to convert the internal image format to fits. The
latter is very important. The internal format is simple. An image
640x480 pixels and 8-bits deep, b/w. jpg, etc. is already done for
writing the internal file. For fits files, I'd like to write very
simple headers that have, say, lat/long of observer, a time stamp, and
some other assorted items.
Items like plotting, manipulating (IP, for example) and displaying are
secondary to the need to write a fits file from the internal file.
