Programmatically insert/format image into CKEditor

[seanzol]

I'm attempting to add some click-to-insert functionality to the editor in 4.1, and I can't seem to find the proper combination of functions to insert and format an image.

I could just insert the <img> tag myself, but then I miss out on the thumbnailing/lightboxing that happens when someone inserts an image by hand. Is there an easy way to tell the editor to parse new content (if I were to just insert the URL), or to pre-process a URL in the same way that CKEditor does it?
