"There is no application set to open this document" error message?

That file format looks corrupted.

Remove the ?b=t off the back end, so the file type reads .jpg

Server side code somehow got amended to the back end (no pun intended) of the file name.

This is their issue not yours, wherever the download came from.

Some images are copyrighted, something to be aware of using downloaded images.

Clean it up and there shouldn't be an issue viewing on your computer as expected.

I tried downloading a few images

"there is no application set to open this document" and allows me to choose an application to open it.

select preview (which I previously used to open downloads and pictures and never had a problem), it won't allow me to.

What are the file types on this hard to open images?

What file format is being used for these particular images?

select preview (which I previously used to open downloads and pictures and never had a problem), it won't allow me to.

They're all .jpg files, and I've never had any trouble open these files before a few days ago.

And what does that mean, "select Preview... it won't allow me to."

Post a screen shot of how far you can get—

Removing the ?b=t solved everything, thank you so much!!

Good computing chasey81 ! Glad this solved your problem. Appreciate the feedback.
