Graham Here is another jquery script this one will embed a youtube channel in your site
the original zip is attached to this post
The original site is HERE
You will need your own api key
You can also upload the main files by remote server
html page http://adgj.mw.lt/youmax-master/youmaxhtml.css
after upload remove the /* and */ and rename it youmax.html
The only changes i have made is to add xt:code tags

javascript http://adgj.mw.lt/youmax-master/js/youmax.js to a folder named js

css http://adgj.mw.lt/youmax-master/css/youmax.css to a folder named css

demo http://adgj.mw.lt/youmax-master/youmax.html

note if you copy a channel url use http NOT https
