Why isn't media respecting my allowed file type settings In my field settings for a media based image field, I have this:



When I upload an image and click next I get the following:



both of those types allow image files, but this particular field should only allow items to be classified as images.  Why is the setting not being respected?
My guess based on my own experience is that the uploaded file shares the same mime type as the publication files configuration, and the system is asking the user which file type to designate. Example, if both types allow for PNGs, it won't be able to determine the file type for you. Try uploading a file who's mimetype isn't shared by others; you won't get that dialog.
