I have a post with two external images. One of them the image name ends with .png , while the other one ends with ".jpg?13134434454323"
I am assuming this is why the plugin won't try to import the image?
As a suggestion, the plugin should still try to get (and process) the file, and not give up until it fails. Or perhaps it could ask the user what kind of file it is?
Thank you for your effort. I just installed the plugin a few minutes ago, and it seems that it will really help me out.
