404 errors...but they are labelled as images

This is my first attempt to speed up a website in this way.
I understand from the tests that I need to reduce image sizes on my site, however, I getting several major errors.

They are indicated as 404 errors…but they are labelled as images in the test results.

When I copy those images shown into a browser…it instead pulls up a web page showing “page cannot be found”.
How can I correct this…it’s obviously not really an image but the pages ARE associated with 3 separate images.

I’m confused.

Help will be apprecitated.


My guess is you’ve got a 404 handler that serves a custom not-found page and as the images are missing then this is being served instead of the images.

Are the images actually on the server?
