Don't worry. I didn't use that part of it. I didn't copy your code. Just looked through the URLs for the API and the icons.
My icon is coming from:
http://i.uk.imwx.com/global/images/93x93/" & tempCode & ".png"
Where tempCode is the values specified for the "code" under the "conditions" block.
EDIT:
Didn't even realize you had a separate sub for getting more icons. I'll take a look into that part of it today. I looked at weather.com, but couldn't find a way to look up their codes (like UKXX1090) without a dev key.
