When the list of Permitted upload file extensions: is changed to allow bmp, or tiff, the module throws an error, and oddly adds additional commas between all of the existing file extensions.
1) configure an image field
2) attempt to add tiff to the list
3) note error, then note list (now says png,, gif,, jpg,, jpeg,, tiff)
4) delete tiff, replace with bmp, try to save again
5) note error, the note list (now says png,,, gif,,, jpg,,, jpeg,,, bmp)
