What sort of post are you making that you want to post screenshots?
There aren’t very many good reasons for posting screenshots, and
screenshots of code is almost never one of them. If you are doing GUI
programming, and the visual layout and look of your widgets are not
correct, then it makes sense to post a screenshot of the widgets.
But code is text, and unless you edit your code using Photoshop, you
should not post it as an image:
if we have to run your code, we have to retype it from scratch, which
may introduce new errors;
screen readers don’t work with images, so posting code as text
discriminates against the blind and visually impaired, who may not be
able to view the image and cannot contribute to the discussion;
users who are reading this via email see only something like this:
There is an easy work-around to the “one inline image per post” rule:
post your screenshots on Imgur and link to the album or gallery. Or post
one image, then reply to it with the second image.
Or better still, don’t use screenshots unless absolutely necessary.
In my time on Discuss here, I have seen probably multiple dozens of
screenshots, and perhaps one or two that actually added to the
discussion rather than were an attractive nuisance that saves the poster
a few seconds at the cost of everyone else.
