Can you recommend any program for collecting likes on Facebook photos?
Or how do you collect likes for win games on Facebook?
A simple prompt along the lines of "If you like the photo, please click 'like', it would mean a lot to me" would increase numbers. A lot of people who see images they like, often don't bother clicking, but would if asked.
Then, no. It sounds like you are spamming people with photos in order to win a competition, which is pretty much the reason we all hate facebook. Regardless, there is no way to cheat the number of likes. You just have to post better pictures.
Or get a lot more friends on facebook who are willing to like your pictures (which is why facebook encourages those types of competitions).
Can you explain what that even means? Do you want to know how to get more people to like your photos? Or do you want to somehow harvest/scrape the information for who has liked them?
If it's the former, you need to… post better pictures.
