Mads Hansen commented on TIKA-519:
----------------------------------

You could also avoid generating temporary files by utilizing the Data URI 
Scheme [http://en.wikipedia.org/wiki/Data_URI_scheme] to embed the (base64 
encoded) image data inline in the @src attribute of the img element.

> Display embedded images in the GUI Formatted Text pane where they occur in 
> the document

> Some parsers are now able to generate img tags in their HTML, in the spot 
> where an embedded image lives
> I think it would be nice to show these images in the GUI in the graphical 
> view. The attached patch will allow the GUI to spot when an embedded: img 
> link is found, re-write it to be in a URL to the temporary directory, and 
> also request the recursing parser capture it.
> The result is that you can drop a suitable file (eg .docx) onto the gui, and 
> in the Formatted Text pane see the image inline
> Are people happy with the patch? (and the idea?)
