The guide!

You are most welcome :)

If you want to make the guide clickable to take people straight to https://www.niwa.co.nz/coasts-and-oceans/marine-identification-guides-and-fact-sheets/beautiful-browns then in front of the code you have for the cover image above put:

GREATER_THAN_SIGNa href="https://www.niwa.co.nz/coasts-and-oceans/marine-identification-guides-and-fact-sheets/beautiful-browns"LESS_THAN_SIGNYour code for the image above will go hereGREATER_THAN_SIGN/aLESS_THAN_SIGN

Here is an example but you just replace the visit text with the image code :)
