Screen shot your settings, I have a feeling you have it configured right. The scrape photo area you have populated with "FLC:" should be populating with new users that it will go through and like their photo. Scrape # for photos should be how many photos from each user you want to 'like' from their account. 1-3 should be sufficient in that area.
Without a screenshot, we have no idea if you have it set up correctly.
