I created a PNG image using MS Paint to use in my document (old school I know). I would like to keep the figure within the page width without losing image quality. I have tried using a JPG image instead but the quality is still poor (in that the words are too small to see when viewed in PDF mode at 100 % zoom).
Can someone suggest a solution please? I include my code and 2 screenshots.
Thanks in advance!

Drawings like this, which consist of straight lines with sharp edges, should really be done as vector graphic for a decent result.
In the following a quick and dirty attempt to recreate your first image in inkscape and export it to pdf+tex. The .svg file which can be edited in inkscape can for the moment be found at https://www.dropbox.com/s/4usem6v976o7r8h/drawing.svg?dl=0 and the resulting .pdf at https://www.dropbox.com/s/wsgfuoe018djtln/drawing.pdf?dl=0 (I'll delete them in a few weeks).

If you must use a pixel based format, choose .png rather then .jpg.
Furthermore consider to export the image without text and add the text in latex. This will have several advantages, for example the text has the same size and font as the surrounding text and it can be searched for in the .pdf
