I've implemented your idea, thanks!
Two additional requests, if I may:
Allow pre-selection of the currency that counters the BTC:
e.g., if I wish to add the widget to my site whose primary readership is in Canada, I might wish to do:
http://bitcoin.1t2l.net/widget/?from=CAD (for CAD to BTC)
and the reverse:
2.) Display the currency symbol:
e.g, The British Pound's is GBP
There appears to be room to also display the currency symbol after the amount.
50 (bitcoins) =
I like it very much. I'm wondering if it is available? I've been looking for a currency converter that convert any currency to BTC for my websites. I hate that I have to manually update prices in BTC currency few times a week.
I am using http://sanescreen.org/converter/
to display the price in BTC currency on the page but I'm unable to use the js/span code in the payment form.
