The issue is that if the image name inside the tag in HTML contains %20, HTML will convert it to a space ( ) and look for the name with a space instead.

In your case, HTML is attempting to find the image at: file:///C:/Users/Anna/Pictures/Nikon%20Transfer/SEALS%20PROJECT/j3evn.jpg

You can try debugging this on your end, but the easiest solution would be to change the folder name.
