Social Media Thumbnail Guidelines 

Behance follows best practices from social networks across the web when it comes to selecting a thumbnail image. Although each social platform is different, here is our methodology behind the thumbnail preview generating when you share a Behance link:

If you are sharing a project page, we generally select the largest and most square static image that appears closest to the top of the page.

• If your project does not have any static images that match the criteria, we'll display your cover image.
• If you would like your project's current cover image to be the thumbnail when shared on social media platforms, we recommend uploading your cover image closest to the top of the project content. 
• This excludes images in Photo Grids

If you are sharing your profile page, you will see your most recent project cover. 

*Note: After you save the changes to your project contents, please refresh and try to preview it again on the social media platform.

Clear Your Thumbnail Cache

If you are having trouble with the thumbnail that is generated on a social media platform, it could be that the image is cached. To get these platforms up to speed with your portfolio changes, use their link debuggers:
