Sara's UssaNabulsiyeh blog does a much better job of describing this situation than I do, so here's a link to her post.
Little Ola will die unless she gets the operation she needs. You can donate funds by going over to the Palestinian Children's Relief Fund site linked here. They take PayPal (the PayPal donation page is simple and quick and linked here), credit cards or even wire transfers. Do mention that your donation is 'for Ola' if you do manage to get over there and make a donation.
We'll be auctioning one of Gerald Donovan's highly popular GigaPan images tonight at GeekFest Dubai in aid of Ola's appeal - a 3' x 3' ultra-high resolution image of the Sheikh Zayed Mosque in Abu Dhabi. Although GeekFest is a resolutely not for charity event, sometimes you just have to do something.
That's it really, there's little more to say.
