All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

* This version applies the function as a filter to the_content rather than send_to_editor. 
* Changes made by filtering send_to_editor will be lost if you update the image or associated post 
* and you will slowly lose your grip on sanity if you don't know to keep an eye out for it. 
* the_content applies to the content of a post after it is retrieved from the database and is "theme-safe".
