I'm presuming you mean that I didn't see it in your email, and I'm
willing to leave it at that.

That's correct. Functions like getimagesize() handle their own
slashing, et cetera.

No, I didn't, actually. I meant "really doesn't exist." If the
file really did exist at that location, it wouldn't be a problem.
That may not be THIS problem, but it is A problem.

Exactly. Interacting with the shell using backticks, exec(),
passthru(), et al, is passed verbatim to the command line configured
with the server's user:group CLI environment. Generally, when passing
arguments, you should escapeshellarg() the arguments. And because the
files were misnamed, that means they didn't exist. You knew which
files you wanted, and to you, it was simple.... but the computer
didn't know it, and when it looked for the files you wanted, they
didn't exist.
