Hi @misbah! If you initially upload your URL or local file with an accompanying id:
img1 = ClImage(url="https://samples.clarifai.com/metro-north.jpg", image_id="train1")
img2 = ClImage(url="https://samples.clarifai.com/puppy.jpeg", image_id="puppy1")
...you can refer to that id later on without having to mention the original filename:
image = app.inputs.get("puppy1")
Is this what you were looking to do?
