Describe the bug

When attempting to upload a PDF file instead of an image in the banner image upload section while creating a post, the system fails to handle the validation correctly. Instead of displaying an appropriate error message, it results in an internal server error.

To Reproduce

Steps to reproduce the behavior:

1. Navigate to the Create Post page.
2. Click on the Banner Image Upload option.
3. Select and upload a PDF file instead of an image (e.g., JPG, PNG).
4. Click on the Submit button.
5. Observe that an internal server error occurs instead of a validation warning.

Expected Behavior

The system should properly validate the uploaded file format and display a relevant error message instead of allowing a non-image file to be uploaded and causing an internal server error.

Additional Context

• The issue suggests a missing validation check for file formats during upload.
• Ideally, the system should restrict accepted formats to image file types only and provide clear feedback if an invalid format is uploaded.
