drag and drop files and get a link and preview in TW5

[stefan infp]

I would like to drag and drop images or other file types into TW5 and automatically get the link to these external files (locally stored) in separate tiddlers. And the preview for images, pdfs,... how can i do that?

Unfortunately, this is no longer allowed by most browsers. While drag and drop provides the content of the file, it no longer provides the source location information, as this could be used in exploits to 'probe' the local directory structure.

Hi Stefan,

Perhaps TiddlyDesktop could at some point provide an enhanced DnD wizard,

essentially a custom browser add-on / interface.

Hi Tobias

That's what I thought, but it turns out to be quite hard to intercept and augment the drag and drop events.

But there is an interesting workaround that we might also explore more: in most browsers, you can open a browser window to show you a directory listing, eg:

file://localhost/Users/jeremy/

In most browsers, dragging one of those entries into TiddlyWiki will create a tiddler containing the URL of the file. With a bit of work, we could turn that into a tiddler with the URL in the _canonical_uri field.

Best wishes

Unfortunately this won't work from an embedded iframe, though.
