At last I got my WeatherIcon working. I also got the image to show up which wouldn’t yesterday 
. If anyone has any doubts about whether they should use Firefox instead of IE as their browser……take it from me, do it!! I found out the reason I couldn’t get the weather to show up was because I was using IE for my WP admin…big no no!
Am I alone in that I have good days and bad days with this? Yesterday I couldn’t get anything to work right, today everything’s gone like a dream. I’ve created lots of themes using templates from Marina and Artie, thank you…you clever, clever people!
Anyway, it’s the weekend and I must try not to spend too much time on here and spend a bit more time with my poor long suffering partner, lol! 
I love your theme; the colors and the fonts and the graphics all work together so well! I see you’re in Cambridge, so I’m green with envy. (I’m an English teacher lol.) Maybe the Explorer thing explains some problems I’ve had, but my school board bought this laptop, and they have some kind of thing against Firefox. Ironically, they admit to using Firefox when Explorer gives trouble. Wish I could help with the moods.
