# Appendix

## 1. Guideline on Images

Images are essential in both giving your VC a recognizable branding as well as a vibrant display of the holder’s achievements.

We support images at 2 levels as elaborated above:

1. At the Top Level of the credential payload
2. At the Credential Subject level

**At the Credential Payload Level**

This would be an image of the logo for your institute. We recommend a square aspect ratio with no less than 1300px \* 1300px in resolution for best visual presentation.

**At the Credential Subject Level**

This would be an image that best represents the specific achievement represented by this credential. It can be a badge, a trophy, a certificate, a mascot … you name it. But please make sure the image DOES NOT:

1. Contain personal identification information that was not intended to go public.
2. Contain visual intellectual properties that you are not legally allowed to use or distribute.

We understand your need to have flexibility to best represent the kind of achievement specific to your program. Our guideline is follow an aspect ratio of 4:3 (for landscape) or 3:4 (for portrait) images as close as possible for the best visual result.
