Must be something to do with the Photobucket app on my iPad. When I click on your image that displays fine Firko it takes me to your photobucket album and then tells me "Safari can't open the page because the address is invalid. " The error message keeps appearing and I can't accept it nor delete it. Can't get out to the endless loop so have to power the iPad down.
Does the same with my own images too. Seems to not recognize there is a photo there even though I can see it plan as day on the screen.
Expect there may be a bug fix appearing anyday soon
