[CDash] Question about displayImage.php

[Elvis Stansvik]

Hi folks,

Quite a while ago, I migrated our CDash into Docker and updated to
what was at the time (Jan 2022) the latest version version from Git
master.

Now that I look back, I see that I've left a bunch of local changes in
the source tree. I think I was attempting to fix some issue, but then
was abruptly occupied by something else, and left things in a bit of a
mess.

The changes I made are all of the form

I.e. they switch from using displayImage.php to using image/ when
referring to images to be displayed.

Now this is a strange question: I have no memory of why I had to do
this. Perhaps I was preparing what I thought was some fix and intended
to submit it as a PR.. (?) Before I dig any further, I just thought
I'd ask people familiar with the code base: Can anyone see a reason
for why I would have had to make these changes? I think it must have
been to solve some issue I was having.

I.e. can anyone help me re-jug my memory about this? :P Would changes
like these make sense for upstream CDash?

Cheers,
Elvis
