I've moved your post to a new thread so you could clarify the issue being mentioned. It's preferred to avoid posting to a thread that is several years old as the issue mentioned might be new and unrelated to the prior discussion.
Can you please provide steps to let us know how you are trying to upload the image? It might be the image type that isn't working. Once we know the extension you are trying to upload as well as any error messages, we can help further.
