Using the HTMLTemplate to display IMG tags

I am working with a KanbanboardItem and trying to render HTML of an image

KanBan.ItemsAppearance.HTMLTemplate := '<b><#TaskName></b><img src="<#ImageSrc>">';

//some where later in my code
Item.HTMLTemplateItems.AddPair('ImageSrc', 'res://sprint1');

The image does not render or show as expected. I have also tried tags and they don't render or show either.

image

The TaskName is working fine from variable, even hardcoding image src into the template is not giving any results. I have also updated and compiled latest components. What am I missing?

So the "file://" src works as expected
