ximage is interactive if you have to adjust the exposure of the image
first. I think you could use pfilt on the image first to get a
reasonable exposure adjustment that displays nicely without further
tweaking. A pfilt preprocess will help with oversized image, too.

xwd is only one app to create screenshots. On Linux you have plenty of
other choices. I would have thought the biggest problem would be to
identify the window. If you can use the image name, fine.

As long as you use a screenshot based method you will always have to
keep the screen free of other windows. If you can't find the time to
let the computer run for a while and you need to do this type of
highlighting a few times you should invest some time in a script that
replaces xglaresrc without ximage. It really doesn't seem that
complicated. Initially I even thought it was a shell script ...

You should reduce the size of large images to something that fits on
your screen. Remember to run findglare again on the smaller size
image! xglaresrc uses a fixed text height and if you have a huge image
the text labels will look tiny.

Problem solved then.
