DownloadFile pictures not in format

I used the DownloadFile Formula to change the names of pictures that are in an web URL but when they get created Windows and any other program says the format is not supported. Also they all have the same size of 41KB which shouldn't be happening. Please help.

Can you provide an example image URL and your DownloadFile formula?

I'm having the same sort of issue. From what I can see, everything is setup correctly and the download goes through but when I try to open up the image, I get this error. Are you getting this error message?
I use paint.net but it doesn't matter which program I use to open the file, it always throws an error.error
