A Wrong Photo Blocks the Form, Not Just the Application
This is what makes IBPS different from most exam uploads.
Annexure IV opens with the sentence that matters most: "until photographs and signatures are as per the specifications provided, the system will not allow the candidate to move forward to the next stage of application." Most portals accept whatever you give them and reject you weeks later. IBPS refuses to let you continue.
In practice that means you cannot leave the photo for last. If the registration window is closing and your image will not pass, you do not have an application at all — not a flawed one.
