I'm new to followerliker myself and only started using the pic upload feature yesterday, however, this is what i THINK should be the settings.
Share limit: 3 - 3 (i'm not 100% certain on this)
Daily share limit: 3 - 3
Delay share: 10800 - 14400 (translates to 3-4hrs)
I wasn't quite sure about the time period which you wanted pictures to be posted, so I assume it was 8:00 - 20:00 which is a 12 hour difference. You wanted 3 pictures to be posted, so the maximum delay was set to 4hours. (So if the bot decides to post all three images with the longest delay of 4hours, all three images would still get posted in your time period)
Once you put these settings in, I believe the next page is where you can set the times you would like the images to be posted.
