There is nothing in the console below about CORS messages or anything? Can you click over to network and check the status of the image request that failed. You can search for y3c.png to help find the request.

From the looks of it you are self hosted since the request for the image is not to growthbook nor it's cdn. The most common reason your problem occurs is because CORS settings are not being set correctly. Perhaps this might because you are storing the files on s3 and sometimes s3 doesn't add the CORS headers even when it is set correctly. Alternatively the bucket has been made private. Setting USE_FILE_PROXY to true might be able to fix the issues. Here is more information on the env vars for configuring file uploads: https://docs.growthbook.io/self-host/env#file-uploads
