Agent keeps choking on large images

The codebase has large images. For some reason, whenever anything even close to these images is mentioned, the agent starts analyzing them and github comes back with:

Sorry, your request failed. Please try again. Copilot Request id: 2aabc57b-f5b7-404d-a303-c936afad452a GH Request Id: 921A:29FA82:ECE6DD:1064850:69D81007 Reason: Request Failed: 400 {"message":"messages.3.content.6.image.source.base64.data: At least one of the image dimensions exceed max allowed size: 8000 pixels"}

So how do I make sure it doesn't do this?
