Presumably you generate the links to the files to put into HTML or CSS at some point? Rather than check if an appropriate sized image is available then the image is requested, why not check when you generate the link to the the image? If when you generate the link it is NOT available, do the necessary stuff to generate it and upload to AWS, then carry on.
