Size Limitations

Content

All,

We are in the process of updating our header (image) within our communication messages. With that being said, does anyone know if there are any image size restrictions that we may be limited to when including in messages? Does this hinder the message restrictions like attachments do? Just trying to get some best practices/feedback and/or if anyone has found anything in the knowledge base that outlines what can or cannot be done when updating messages at the global level.
