I have a problem with integration Lazy Load Plugin, written by Mika Tuupola, in CKEditor. Firstly, I tried to use that solution, but it seems too difficult to me. I meen, there's no necessary to enable checkbox to add plugin functionality, better to do that automatically. But this became main problem to me, about how to replace "src" attribute of "img" tags to "data-original" attribute, as it requires in Lazy Load Plugin. Note, that replacement is needed just in front-end, because in admin panel, in ckeditor, img tags are used with src attribute.
I would very glad for any idea. Thanks.
