Message attachments?

I need to attach my logo file to a message to a seller so that my order can be customized. There seems to be no way to do this. Suggestions?

Go to your Purchase history.  Locate the transaction, click on CONTACT SELLER.  When you create your message there should be a link to add a photo.  I believe it should be in JPG format.
