Hello @ScottG626. Thank you for pointing that out. We'll bring this up with our Knowledge Base team.
Your campaign is using our third-generation editor which has a 256-character limit for alt text. We may be able to convert this campaign to our cross-platform editor so you can have access to the expanded character limit. Please contact our Support team who can submit a request to our upper level of support. You can also select a new template by clicking Create on the campaign page as the picker page includes templates using that new editor.
