Sorry BD ..... I didn't realise the width caused the problems .... yours (your picture)also is doing the same to me this end, if I was inconsiderate, it was inadvertent. I can't figure out how to edit it to delete the pic. will send a PM to Robert.
My point was that what you see in one photo from one angle can appear totally different from another angle, and resolution. The photos are not re-touched..... the early ones were taken of mars in 1976 ... the last with better cameras and closer orbits last year.
If you go to the APOD site and type in Mars you will get about 500 photos of Mars alone.
