Pictures somehow got pasted in my assembly

I am using Solidworks 2025. Somehow, my assembly has repeating picture showing on each part. I don't know how it got there, or how to remove it. It was kinda funny for a while, but I need to send a snapshot to the customer, and it's embarrasing. I've tried removing all appearances in assembly. Looked all through the View menu. I can't find solution.

Help.
