Hi,
Try the following code:
"{{$:/core/images/chevron-down}} vs. [img[$:/core/images/chevron-down]]"For me, on TW 5.1.19, the second way does not render anything. I did not dig deeper, but could it be that the name of the core image is interpreted as external URL by the widget instead of tiddler name?
I guess it is possible to mirror the behaviour of the image widget with its height and width attributes using transclusion and CSS as in
