Getting Browser Widget to Read Local Assets

BR,

assuming you don't have a local server running:

It is an essential difference whether you set the htmltext or
set the URL of the widget.

If the image is called in the htmltext then there is no way but
using a dataURL (=inline image), no matter if it is an img tag or
called in the style tag. But that works always.

If you save the same htmltext to a html file then the image from
a local path that is *relative* to that file is loaded.

There are very few cases where *absolute* file:// - syntax works
and there will be increasing less cases.

If the image becomes "tinted" (by acting on it's data), then you
will need a local server running that calls that html file.

If you use a video file instead of an image (or a webcam) then
you will need a https - connection to your local server. This is
very hard to install except you use a solution like the commercial
MAMP Pro (assuming you are on Mac).

Also look at the following:

You have to fill the placeholder <b64Data>, for instance this way:
...(replace line ** in mouseUp):
set the htmltext of  widget "browser" to merge(fld "html")
...
and then in the html:
background-image: url('data:image/jpg;base64,[[b64Data]]')
