I signed onto Google+. It offered to import photos from Picasa. I said yes, not knowing I had anything on there. It imported a bunch of screenshots, which are images hosted on my blogger blog. This makes no sense being on my Google+ page, so I deleted the album within Google+. However, it looks like it has also wiped the album from Picasa. All my images from 5 years of blogging deleted without so much as an "are you sure"? Is there a way I can get them back?
