Topic: Bug report - minor
First question - where do you post possible bug reports? or do you prefer direct email?
Now the possble bug (feature - smile) ...
If there is only one photo in a gallery clicking forward or backward confuses Simple Viewer.
After checking - this is only a problem if looping is enabled. Maybe check for number of images and disable looping if only one image?
Not something that will happen often but maybe it could be trapped.
