what does it say?
I can only tell you what I know see. You asked a question about the forward process and I answered with how it is suppose to work. There is no issue that I see with the process. I do understand you expect it to work a different way but that is not going to change my answer to you.
On a singular upload you are sent to the image. On multiple uploads the upload process simply process all files and then ends on the upload script with nothing else left to process. You would then use the normal navigation of the application if you want to go elsewhere.
