##################
two problems with the above code.
1. def unique_file_gallerythumb(instance, file_name):
if you interogate the file_name in debug, it comtains two suffixes.
wedding.jpg.jpg is the uploaded file. quite strange. hance im using
splitext twice.
2. the line below creates an empty copy of the image in the root
folder, the one that the settings file lives in. empty as in zero kb.
self.gallerythumb.save(suf.name+'.jpg', suf, save=False)
anyone see any obvious reasons why the above would be happening?
