Bug Report: Model Creation Requires Image File Upload Despite Using Remote URL

[whomingbird]

When creating a model using a remote URL, the system incorrectly prompts for an image/file upload. This is unexpected behavior, as the remote URL should be sufficient for the model creation process.

The issue appears to stem from user behavior rather than a code-related bug. To clarify, users need to click the "Add" button to confirm adding the file before submitting. However, it's possible for users unfamiliar with the interface to overlook this step. Adding additional highlighted text would help remind users to click the "Add" button before proceeding.
