1. Unsupported picture format: Some student loan application systems only support specific picture formats, such as JPEG and PNG. If the uploaded photo format does not meet the requirements, the system cannot identify and process it.
2. The picture size exceeds the limit: the student loan application system often has certain restrictions on the size of uploaded photos. If the photo size is too large, the system may not be able to handle it.
3. Unstable network connection: uploading photos depends on network connection. If the network is unstable or interrupted, the photo upload and display will be incomplete.
