Hello,
Last week I started to build a WordPress theme with a mobile first approach but couldn’t find any good solution/plugin for loading smaller content images for mobile devices. Scaling them down with css wasn’t good enough.
With some help from a couple of other libraries I made a plugin that ables you to swap the content images with a smaller version server side. I thought that maybe someone else had the same issue so I released it as a (my first) official WordPress plugin.
If anyone got time, please test it and let me know what you think. I haven’t had much time to test it so please let me know if you find any bugs.
Any suggestions to make the plugin better are more than welcome.
you can find the plugin here

Many thanks
Erik
