Lack of interest Show error message if upload process is nearing max_execution_time

[AndyB]

Sometimes users will try to upload an image from their mobile phone when upload speeds are very slow. This can result in a server error log if max_execution_time is reached. Instead of throwing a server error, why not terminate the upload process with an error message indicating "upload is taking too long" when the upload is nearing the max_execution_time.
