OneForAll uses PLUPLOAD to handle the upload of images.
What needs to be changed to have PLUPLOAD handle/alter the filename upon saving? It refuses filenames with special characters (copyright-sign, for instance) and does not replace spaces (should be, to avoid validation errors).
Also, I've noticed that PLUPLOAD does not accept large files. If I try to upload an image of say 9 MB, it will come back with the error "Filename already exists".
Then, when I save the OFA-item and go back into it, I see that the large image was in fact partially saved.
Something goes wrong with the storing of the file, it seems.
