Compatibility with Customizr Theme

If your images aren't showing up on your website after hitting the "Save and Update" button, you could be experiencing an issue with the Customizer, a child theme of the Cuztomizr theme.

If you have these image settings ticked on the Customizr theme (the lazy load setting especially) they override certain commands within your site. This might be why your images don't show up when these settings are turned on. 

To disable them, just go to  Appearance > Themes > Customizr > Customize > Advanced Options > Website Performances, and uncheck the "lazy load the images in sliders" and "load images on scroll" options.
