Abstract: Systems and methods are provided for processing images (or other such instances of content) to detect which of the images exhibit artifacts when modified, such as by applying standard transformation algorithms to modify the images. Such techniques enable transformation algorithms to be applied to the detected images to minimize or prevent artifacts. In some embodiments, the headers of the detected images can be tagged with transformative instructions that indicate which transformation algorithms to apply. Responsive to a request from a web client to modify and render one of the detected images, embodiments obtain the requested image, read the transformative instructions in the header, apply the transformation algorithm specified in the header to modify the image so as to minimize or prevent artifacts, and render the modified image.
