Upload once, paste the tag into a Streak snippet. URLs are permanent.
Copy image is the one you want for a Streak snippet — it puts real HTML
on the clipboard, so the editor pastes a picture. Copy tag puts the source text
on instead, for pasting into an HTML view or a template file; pasted straight into a rich-text
editor it will show up as literal <img …> text.
Width is pre-filled at half the intrinsic size, which is right for a 2× retina asset.
If you uploaded at 1×, hit Full. Many email clients ignore CSS but honour
the width attribute, so the tag always carries one.
Nothing here is ever deleted — a URL may be sitting in mail someone received years ago.
