Image hosting and a media library for templates
Upload a PNG, JPEG, GIF or WebP up to 5 MB and it is published to a permanent public URL on media.sendheron.com, so an email still resolves its images years after it was sent. Past uploads collect in a searchable library that any template can reuse.
app.sendheron.com/templates
Screenshot pending. The media library with a handful of uploads and the search field in use. Demo workspace assets only.
The bytes decide the type, not the file name
Content type is identified from the file's own signature server-side rather than trusting what the browser said it was. A file named photo.png that is not a PNG is refused, which is the only version of this check that is worth having.
SVG is refused outright. It is a legitimate image format and most mail clients will not render it, so accepting it would mean publishing images that quietly fail to appear in exactly the place they matter.
Published assets are permanent
There is no delete path for a published asset, deliberately. An email that has already been delivered keeps pointing at the URL it was sent with, and a broken image in somebody's archive is not a state we can fix later.
