Recently I decided to improve my WordPress photo gallery. The goal was to improve my pictures when viewed with the new high-end retina or 4K displays. This post covers some of the challenges I encountered and image technology improvements that WordPress now offers.
A 4K screen means 4000 pixels across and now there are even 5K displays available. Apple’s retina iMac display has 5220 pixels. The upper end of TVs now boast 4K as the new hi-def plateau in picture resolution. If you have professional photography or artwork that you want to present visually at the highest quality, then, you may need to upload higher resolution images to display optimally on these new retina/4K/5K displays. Retina images (so called 2x images) double the amount of pixels that your image will be displayed at (e.g 200 x 200 pixels), and inserting the 2x image into half of that space (100 x 100 pixels). In many ways using web images has become more complex and having the optimal images delivered to the many different types of internet devices has become tricky. Internet devices come in many sizes now, some displays are retina quality and others are not. So what size of image is going to work with such a wide range of internet devices/displays? The answer is no image size will work effectively for all the possible devices and display resolutions.
