Your linked image
The image shows the current month in the calendar's timezone. It updates automatically and clicking it opens the interactive availability page.
Example image HTML
<a href="https://dobu.uk/availability/your-nickname"><img src="https://dobu.uk/embed/availability/your-nickname/calendar.svg" alt="View availability calendar" width="480" height="650" loading="lazy" style="display:block;width:100%;max-width:480px;height:auto;border:0"></a>
Replace your-nickname with the nickname of the DoBu.uk profile you want to embed.
Preview
This example uses the richiejp profile. Select a saved profile above to preview your own calendar.
How it behaves
This is a normal SVG image, so it needs no iframe or JavaScript and scales with the available width without being cropped. Browsers and the server cache it for five minutes; the next request then picks up changed availability or a new local day.
The image itself is not interactive. Its link opens the live calendar, where the viewer can change month, select a date, and make an enquiry.
