If you take two screenshots of a browser window with
the address bar
visible, in each case with a different url, then of course the image files
will be different. That's only logical.
Also if you save to a file format that saves the modification date+time in
some metadata like EXIF, then your md5sum will be different too.
Does not matter, for the webserver a image file is binary content,
different md5sum --> should not expect indentical results, period.
To compare images, you could use imgcmp:
$ imgcmp -f 3111skyline-nemesis.jpg -F 3111skyline-ecstasy.jpg -m rmse
Now you are making something very simple to verify unnecessarily complex
and bug prone..
