My plan was to use the wp srcset function to deliver the best sized images to the Website users. In all threads you say that xtheme uses its own mechanismn. But on my webpage the image size is always fullres. As i need photo galleries on my site with many images this results in long loading times with alot of data used . How can i change that behaviour. E.g. When using envira gallery.
X theme uses it’s own responsive feature when serving images. But it’s not connected how Envira Gallery serve their images. It has its own setting on what size of the image you wish to display. It’s under Config > Image Size.
