When I was writing a theme before, the problem of fixing the size of thumbnails has always puzzled me. Fixed image width and height will cause image deformation. If a very long rectangular image is fixed as a square, the entire image will become blurred and cannot be seen at all. Later, the thumbnail plug-in was used to cut and generate fixed size thumbnails to solve this problem. But after a while, it was found that the thumbnail page generated by the plug-in could not be cached. If a page has many thumbnails, it would be very bad ..
