    Important You can add up to 10 messages within one carousel, but all messages in a carousel must have the same number of images, buttons, and fields.
5. To add an image, click **Browse** or add a URL.
    
    Use a JPEG or PNG image with a maximum 1024-px width. The image URL maximum is 1,000 characters.
6. Add a title to your message. The maximum character count for the title is 40.
7. Enter your message, up to 60 characters.
    
    You can use AMPscript in all message fields, which doesn’t count toward the character limit.
    
    If you exceed the height limit, the lower part of the text display area is cut off. For this reason, depending on the character width, the message text might not fully display even when it is within the character limit.

    1. Add labels for each button. Button label maximum is 20 characters.
