For no reason that I can think of, after not having used Dreamweaver for a while, when wanting to insert images it won't accept some of the images. Cannot see any obvious reason for not wanting to insert certain images..as they are all .jpg-files.. Error message says: "Dreamweaver cannot open .jpg files. Please choose an XML, HTML or other compatible file"

What is wrong? Have tried removing software and also re-intalling. Very annoying..
