look at the file extension type. The file extension is usually at the end of the filename. An example would be "picture.jpeg" or "picture.jpg" where "picture" is what you've named it and ".jpeg" or ".jpg" is the file extension type. PB only works with certain filetypes and while I'm not sure of all the file types that PB works with, I know it works with jpeg files. So you might want to try opening the picture on your computer, click on file (upper left side), then click "save as" on the menu that dropped down, then when the window pops up where you name the file and choose the location to save it in, make sure the filetype below (right below where you named the file) says jpeg or jpg. There should be a drop down box that once you click it will give you some options. Hope that is a little clearer than muddy water! ;D
