Upload image - but save image directly in jHtmlArea

Having tried several ways to upload and save images in jHtmlArea, I ended up with this solution.
The image is uploaded to the server and converted to data to insert in the src attribute of the <img/> object.

All image data are hereafter in the jHtmlArea document.

The solution is inspired by Eric Bidelman's solution here:

OBS! There is a problem with Safari - please help me!

Update 01/17/2014:
New download - Safir problem fixed; image resize implemented


Check the jHtmlArea html-content using the left button in the toolbar.


Next plan is to resize the image before sending data back.
Any suggstions are appreciated.

Hope you like it.

Now - without upload!

Using HTM5 you can read the local image file and resize it on the client-side. then insert the imageurl directly and the image is embedded in the edited tet. Uploading and saving the image is not required.
