When inserting Image item, use a link instead of embeded image.

I usually insert my company logo on each report, it is embeded, but now the company change logo, and I need to replace it on all reports (arround 1800 on my last count), I really would like it to be an url, so I can just change the source image insted.

I know with HTML code I can change it, but it will require to storage the image, on a different webserver, so it will be nice if there could be a folder already set on the spotfire for public access to put those images and use their url.  This folder can also work for other purposes (eg, if somebody want to download it as compressed file, spotfire will put it there as temporary to generate the URL so the public can download it.   I will work also with writte to excel pyton scripts that has been around for some time.
