Unable to upload avatar due to file size

Uploading an image to change my avatar says my image is too big because it exceeds 256KB. Windows shows that the image is 237 KB in size and 240 KB size on disk. Cropping the image as much as I can still doesn't work.

This is the error message:

This is the file size:

I see it as your avatar now, did the issue resolve itself?

I uploaded a smaller version of it.
