Interesting...
Now, the address of that image is in my Photobucket account. The image still shows up on the thread where I posted it yesterday, and I snagged the address embedded in it to post it to this thread.
That's got to mean the account's still there, otherwise the image would have de-linked from FR by now.
Well now, this is different: If I search for “windflier” in PB, I see 24 Texas-related thumbnails, but if I click on any one of them, I get an “image not found” error message, but with the same 24 thumbnails displayed beneath, including the “not found” one.
It seems to be working OK now.
