I would like to be able to use the large image solution pack to display jpgs in order to take advantage of the openseadragon viewer.
The derivatives.inc seems to support the OBJ datastream being either jpg, gif, or png. I have tried all three and they seem to create all the correct datastreams.
The image upload form, however, limits the upload to tiff or jp2.
I propose we add the extension jpg jpeg png and gif to the extensions array in image_upload.
