**Actual Result:**
- When attempting to submit the certification details without uploading a certificate image, an incorrect toaster message is displayed, prompting to enter a certificate URL. This message might confuse the user as the field might not require a URL.

**Expected Result:**
- Upon attempting to submit the certification details without uploading an image, the system should display an accurate and clear toaster message explicitly stating that the certificate image upload is a mandatory field. It should prompt the user to upload the image file to proceed, providing a clear understanding of the missing required information.
