Having a quick look over the site www.film2240.wordpress.com
it appears that the donate by Bitcoin doesn't explain how to donate for those people unfamiliar with Bitcoin. I'd suggest adding some text pointing to lovebitcoins.org
which was suggested as the public face of Bitcoin for mainstream access at the Prague conference.
The Bitcoin URI currently encoded into the QR code is a valid address and would show up in a typical mobile client as a suggested donation, the customer/donator is free to change this value to whatever they prefer. The label also helps with tracking for the customer.
The MultiBit (http://multibit.org
) client will support the customer/donator performing a drag and drop payment from the browser so that's also good. However, it is often helpful to provide the raw address since it can be copy/pasted into any client thus making sure you don't accidently exclude some potential donators.
I will be updating my own example to reflect these suggestions, so please accept my apologies for the lack of detail.
