File extension oddity. When exporting a Scribus doc to a JPEG, Scribus uses the file extension ".jpeg". However, when doing a "Get Picture" to fill a picture frame Scribus does not look for the ".jpeg" (or ".jpe") file extension as a valid supported format. Yes, the file type filtering can be turned off but it may be confusing for some users to then see all files (those not images at all).
If nothing else Scribus should show some consistency and export the image with a file extension it considers a valid format so that it can immediately be used as the target of a picture frame without renaming or turning off the "Get Picture" image filtering Also, the picture format filtering should probably be case insensitive as well. Currently ".Jpg" or any other such combinations where the file extension is not all caps or all lower case are missed.
