Isn't initImagePaste has done that?

Sorry, I didn't understand what you mean. Do you mean why I create a new function initSimpleMDEImagePaste to fix the image paste problem? 🤔

@lunny, if you are asking why there is a new initSimpleMDEImagePaste, the reasons are:

  1. The initImagePaste always attached the uploaded file input $('.files'), which is not the correct DOM element for comment. So I need a new function to allow caller providing correct DOM element to attach file.

  2. When I trying to re-use initImagePaste for comment editor, it's weird that the CodeMirror input-field fails to insert image (![img](http://url). Therefore I have to insert the image markdown with simplemde.codemirror.replaceRange.
