Here is what happens: - you render some HTML from a *temporary* component, i.e. this component is not member of the page's component tree - your JS code to renders this HTML - since there are <img> in the HTML additional HTTP calls are made to load them - the image could not be found because there is no such parent component
Consider using ImageResourceReference (from your other mail recently) instead.
