Plex Theme - bug with images containing "ombi" in the file name.

[crunchysoft]

Describe the bug
The Organizr Plex theme has a bug that causes any image, with "ombi" in the name, to be replaced on the Tab page with a generic one.
This issue is not present in the default Organizr theme.

To Reproduce
I've created my own image, and it gets the same background (which is what shows in the tabs on the left).
If I take "ombi" out of the .png file name, then it works normally.

Expected behavior
Any image with "ombi" in the file name, should be treated the same as all others, and not be replaced.
