No, I can't do a permanent fix, I don't even know if the ~original fix still works, but I think I must mention a couple of things.
When PB first realised that their initial attempt at charging customers for 3rd party image hosting was grossly unfair, they took a step back, and replaced all the horrid PB speedo images, with customers original images on whatever sites they were on. This period of grace was for an (unknown to me) certain length of time until PB could come up with a more acceptable pricing structure for 3rd party hosting.
As far as I know, this period of grace is still in existence and, I believe, that is why Dennis' images are still on his profile page. That has nothing to do with me.
I feel certain that this period of grace will end soon, as we've had it for quite some time now, so those speedo images (unless they've come up with another 'Upgrade your account' pic) may start to return at some point.
I'll try the ~original fix again when the PB blocked image placeholders return to our screens, and let you know if it works.
Thanks MM.
