Hi @Jenbn, I have just done this and learnt a few things from the way you structured the tags. Specifically removing the height from the iframe meant that it automatically takes on the correct dimension. Like you I only used an img for the svg however I was doing this locally and had to use a srcset otherwise I got the alt text. I used paint to resise and for the first two images I got a white backgroud. How did you get a red background? Thanks a lot for sharing this. It gave me an opportunity to look if mine was OK.
