Hello @NancyB0316 ,

that's how email inbox text previews work. If an image doesn't have any title / alt text embedded into it, and there's enough room after your name, the subject line, and the preheader, then the email's body text will start to show. 

If you don't want your email's body text to show, you'll either need to make a longer name, a longer subject line, a long preheader, or simply make the text bigger in your email program, as this is how they work.
