Image copyright as a link

A new member who is adding some fantastic images to Numista tried to include his personal website as the copyright for an image so it would display as a link. The two pages are here and here. The code they used was:

<a href="https://www.irishpapermoney.com"; style="color:black;" target="_blank" rel="noopener">Irish Paper Money</a>

but this is just displays directly on the pages rather than being interpreted as a link. I'm no expert on such matters, so it may be that there is a bug in the code that's preventing it from working. However, if that's not the case, can I suggest that links be permitted in this field?

You only get a link if the source is in the list of 'I copied the picture from a website that gave their permission'.

Thanks for the clarification. Hibernia and I are learning as we go here.
