Site maintenance needed

I noticed that most of my posts for this year up to the end of May that had photos are now missing some or all of the images. As I realized late in May, this came from using the easy but dangerous new copy-and-paste method of adding photos to Blogspot posts, which actually just hotlinks to the photo source. If anything changes with the photo source - in this case, the photos I had downloaded to Facebook albums - the link becomes broken, and the photos vanish. Not all of them, not all at once, but enough of them to be a problem requiring that I reupload them all directly to Blogger. So I have a LOT of photos to replace.
