97	+ = THEME & PLUGIN COMPATIBILITY =
98	+
99	+ 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.
100	+
101	+ 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](https://wordpress.org/plugins/a3-lazy-load/#faq-header) of a3 lazy Load filter tags to include in your ticket to make it easy for the developer.
102	+
103	+ Don't forget when a developer does add full compatibility with a3 Lazy Load please let us know via a support ticket on this forum and we will add them to the list below.

139	+ == Frequently Asked Questions ==
140	+
141	+ = How do I exclude individual objects from Lazy Load? =
142	+
143	+ Use this built in class name to exclude lazy load on individual images, videos and iframes.
144	+ <code>a3-notlazy</code>
145	+
146	+ = Why are some images, videos, objects not Lazy Loaded? =
147	+
148	+ a3 Lazy Load can only be applied to objects that are added using core WordPress functions. If your theme or a plugin developer adds objects such as images or videos via a custom written function, a3 lazy Load cannot know what that custom function is and hence cannot Lazy Load the object.
149	+
150	+ So if you see object not being lazy loaded please check first if those objects are loaded by the theme or a plugin. If they are, you can be confident that they are loaded by a custom function.
151	+
152	+ If this is the case, please help yourself and other a3 lazy Load users by raising a support ticket with the developer and ask them to add an a3 Lazy Load filter tag to their function to allow a3 Lazy Load to find it and apply to the object.
153	+
154	+ Below is a list of available a3 Lazy Load filters to use and pass onto the developer.
155	+
156	+ = Filter tags to apply lazy load =
157	+
158	+ Apply lazy load for images in content.
159	+ <code>a3_lazy_load_images</code>
160	+ Example:
161	+ <code>apply_filters( 'a3_lazy_load_images', $your_content, null );</code>
162	+
163	+ Apply lazy load for videos and iframe from content.
164	+ <code>a3_lazy_load_videos</code>
165	+ Example:
166	+ <code>apply_filters( 'a3_lazy_load_videos', $your_content, null );</code>
167	+
168	+ Apply lazy load for all images, videos and iframe from content
169	+ <code>a3_lazy_load_html</code>
170	+ Example:
171	+ <code>apply_filters( 'a3_lazy_load_html', $your_content, null );</code>
172	+
