I see a blank page when using web viewer to display a gif file

Has anyone seeing this issue before? When I touch the screen, the zooming tool kit would be shown at the lower-right corner.

Best Regards,

Whitney

Please show your relevant blocks - you should know this by now!

Also the url or file path to the gif.

I solved it now. Please don't worry about it anymore.

Might be helpful to others to tell us what the problem was and how you solved it?

I found the path for getting the file was wrong. I finally found it in a folder called appinventor.ai and it works.
