Describe the bug
When uploading an image that doesn't meet Hi.Events requirements (e.g., dimensions or file format), the UI displays a generic message:

"Please check the provided information is correct"

This message does not indicate the real issue, which leads to confusion and repeated failed attempts. In addition, it does not provide clarity around the image size requirements, which seemed inconsistent.

To Reproduce
Steps to reproduce the behavior:

1. Navigate to the event Homepage Design section.
2. Upload an image that does not meet expected criteria (e.g.,, wrong aspect ratio or encoding).
3. Observe the generic error message at the top of the screen. Message does not clarify why uploaded image is not supported.

Expected behavior
The error message should clearly explain why the image failed (e.g., "Image must be 2160x1080px and under 5MB").

Additional context
Image I uploaded is 2.7 MBs and dimensions are 1536 × 1024. While I understand the recommendation is 2160x1080, other image sizes (like 1024x1024) are accepted, making it unclear to the user what image size requirements are.
