Admin help on File moderation

I have submitted two image files for a new games module site. I also submitted the module. The module came out of moderation on May 8th. The images did not. Resubmitted the images May 9th. A new wave of files was approved on the 10th yet the images were not among them again.

Can someone tell me if there is an issue with the images??

Image names from the last submission:

As per suggestion from user on FB Vassal group resubmitted under more unique names.

yes - (in general) please use unique names. There are templates / examples / images etc we already have with generic names and we dont necessarily want to break these things.

Unique names are your best friend - they already have been approved
