Camera tool overlapping images

Heya,

I'm having issues with the Camera tool layering the same image ontop of itself frequently, especially when re-opening the file whereby it states:
This workbook contains links to one or more external sources that could be unsafe.
If you trust the links, update them to get the latest data. Otherwise, you can keep working on the data you have.
If I select update, it will layer a new picture on top with source formatting. If I select don't update, it will layer with current formatting. 
It also layers intermittently while working on the workbook, unsure if this is from a specific action... Please help!
