Help with Lightbox Maker

I am trying to upload a small picture into Lightbox Maker to print on my X1C. The picture is small, so it is not bigger than the X1C bed. I upload the file and it displays correct. The popup that displays the image has no “continue” (or anything similar) button to keep going.

I’ve tried multiple files and multiple formats. What am I missing?

The picture attached shows the popup box that is displayed after I uploaded my image.

It appears its there, try restarting your project

Well I feel dumb. I’ve been working in Chrome; when I brought Lightbox Maker in Edge, I see things correctly. Thanks for the help.
