I am always amazed by the support here, thank you. After seeing Brian's code I switched resize_image() to be a model method and then I switched from saving the form to saving the profile
profile = request.user.get_profile() profile.save_picture(pform.cleaned_data['picture'].read()) instead of new_profile = pform.save(commit=False) new_profile.picture.save(filename, thumbnail_content) Merrick On Dec 22, 1:10 pm, brianmac44 <anon1...@gmail.com> wrote: > With my code, what are you using as "content"? > > I'm using: form.cleaned_data['source'].read() > > So my code looks something like this: > PHOTO_MEDIUM_SIZE = 400,400 > source_image = form.cleaned_data['source'].read() > resized_image = resize_photo(source_image,PHOTO_MEDIUM_SIZE)) > photos.save(image_name,resized_image) > > You may want to also want to check the image file you are using for > testing, interlaced PNG's are not supported by > PIL.http://www.pythonware.com/library/pil/handbook/format-png.htm > > -Brian > > On Dec 22, 2:46 pm,Merrick<merr...@gmail.com> wrote: > > > I got the same result with brianmac44's code.
