Question marks showing instead of pictures

Hi. The Pinterest Badge is showing up on my site, and looks great, except for the fact that only little blue question mark boxes show up where the pictures should be.

Please let me know how to rectify this.

Also, is there a way to centralise the badge in my sidebar?

Thanks
