You know what I want? I want a tag that I can use like <img> but more flexibly- I want to manage cache and authentication on images displayed in-browser, and the fact that I basically have to use URL or Cookie auth for image embeds is ridiculous. My entire API uses tokens, except for when it deals with image resources (and those images need to be protected to only display in the correct place, because they're not pictures of cats, but Highly Sensitive pictures of Important Cats).
