How to optimize slider image size (desktop, tablet, mobile). At the moment I have a desktop image 1600×500. What is the correct image size for tablet and mobile?
The featured image (https://take.ms/WN0rx) of the slide may be cut in mobile devices due to the background image nature, thus there may be necessary to set different size images on the background for tablet and mobile (https://take.ms/nYnOi). Slide image on the tablet and Slide image on mobile provides the option to set different image sizes and make the slider responsive on all the devices.
