tw5 - Field value as image url ?

[Måns]

Hi TwWizards

I'm trying to do sth like this: [img[{{!!title}}|{{!!image}}]] where image is a custom field value... However it doesn't work... (I'm using TW5 5.0.10-beta)

I also tried to input the fieldvalue (an external image url) into the icon via the TagManager - which doesn't work either...

Should I expect something like this to be possible in the near future?

Cheers Måns Mårtensson

To do this you need to use the raw <$image> widget:

<$image source={{!!image}} tooltip={{!!title}}/>

See http://tiddlywiki.com/static/ImageWidget.html

Hi Jeremy

Thank you.

Are there any plans to let the icon field value accept/use external images (via URLs http or file)?

eg. icon: http://somedomain.com/someimage.png

Hi Måns

Are there any plans to let the icon field value accept/use external images (via URLs http or file)?

eg. icon: http://somedomain.com/someimage.png

At the moment, the templates use transclusion for the icon:

https://github.com/Jermolene/TiddlyWiki5/blob/master/core/ui/ViewTemplate/title.tid#L14

https://github.com/Jermolene/TiddlyWiki5/blob/master/core/ui/TagTemplate.tid#L9

We could switch it to use the <$image> widget instead, which does understand how to embed remote image URIs. However, the <$image> widget can't display images that are actually wikitext tiddlers containing SVG tags (eg, $:/core/images/delete-button).

So, as things stand we have a tradeoff:

* Stick with transclusion, allowing us to use images and wikitext images

* Switch to the image widget, losing the ability to use wikitext images

There is a workaround, though: create a "stub" tiddler representing the remote image, with the text containing a reference to the remote image (eg `[img[http://blah.com/blah.jpg]]`. If you give it the tag $:/tags/Image then it will be recognised by the tag manager as an image and included in the image dropdowns.

Hi Jeremy

Thank you very much!

That was a very neat trick :-)

Now I have one up my sleeve too :-):

I made a template tiddler "TitleImageTemplate" tagged it with $:/tags/Image and wrote this text: "<$image source={{!!image}} tooltip={{!!title}}/>".

This seems to work just how I wanted it to work! (in Chrome - haven't tested other browsers yet..) - except I still have to choose the icon manually for all tiddlers which should use the template.

Next thing I'd like to do is to make it work on all tiddlers tagged with e.g. "teacher"...
