THEME & PLUGIN COMPATIBILITY

a3 Lazy Load works with any WordPress theme that follows the WordPress Theme Codex. However, many Theme & Plugin developers will use a custom written function to add objects, example the theme has a home page with layout created by a custom function they have written. a3 Lazy Load cannot know what these functions are and so cannot apply to the objects loaded by that custom function.

If your images or objects not being Lazy Loaded in a certain section of your site, but are Lazy Loaded everywhere else you will know this is the cause. Please if this happens raise a support ticket with the developer, explaining that they just need to add a simple tag to their custom functions so that a3 Lazy Load apply to their custom function and be fully compatible. Here is a list of a3 lazy Load filter tags to include in your ticket to make it easy for the developer.
