On a PHP based website, i would like to display uploaded images of insects in their natural proportion to one another: even though the image of an ant and the image of a bumblebee have the same resolution, the absolute count of screen-pixels should differ, the image of the bumblebee should be displayed larger. How can i scale the images automatically with PHP/CSS? Can I use EXIF data? Maybe there are already existing solutions, but i didn't find them online.
