I’ve created a component to use bundled images by filename from JavaScript.
Now you can write something like:
<Each Items="{files}">
<Image>
<JSBundleImageSource File="{}" />
</Image>
</Each>
From a structure like this:
var files = ['Assets/Oslo.jpg','Assets/Paris.jpg'];
Just add JSBundleImageSource.uno
to your project, or reference it from your unoproj file.
