I used the search but couldn't get the right answer for my issue.
I developped a theme, which on the portfolio template take the selected featured image of the different portfolio items and crop them to a fixed size (add_image_size) to make them fit to the general grid. Until here no Problem ;)
But what if I want to make all custom uploaded images "retina ready". I know there are some scripts (
retina.js) which search on the server if there are a bigger/@2x version of the image and take them.
But if the image is cropped by the
the_post_thumbnail('custom-thumb'); ) function, the double/bigger image will have no effect on it?
Am I right? How can I solve this issue?
