Hi Tomás
Very informative webcast. Love the way you wrap the Google Image API!
One note though. It would have been nice, if the screencast output were a bit larger (Running Ubuntu with Firefox)
Best regards,

I wasn’t too happy with the resolution either. I am gonna explore YouTube and see if I can take advantage of it’s more generous video sizes
