If the photo is taken from a video of a major studio it's likely that this photo is on other sites as well and some may have the title. With some reverse image search (search on google and you can find several sites) you can insert your image (or a link to an image) and they find all the same image (or in some case similar) to your image.
Obviously if the photos is from amateurs is difficult because maybe they are taken from protected sites or are screenshot from a clip, but for images like that you can find them on the sites like justusboys, waybig and similar that publicize the videos from the studios.

Hmm… I think I did the same thing, searching by image on Google. Unfortunately, I couldn't find what I need.
Anyway, thank you for your help.

Wow. Thanks, Aleedinver. That helps me so much.
How did you find it? Can you explain it in more details?
