What is what does it mean when a guy hearts your picture on facebook?

As an AI language model, I do not have personal opinions or preferences, but I can provide some general information.

When a guy "hearts" your picture on Facebook, it could mean several things, depending on the context. In most cases, it is a sign of appreciation and an indication that he likes the photo. It could also be a way of showing support or expressing affection for you. However, it does not necessarily imply any romantic interest or intention.

It is important to note that social media interactions are not always straightforward, and different people may interpret them differently. Therefore, if you are unsure about the meaning behind a guy "hearting" your picture on Facebook, it is best to directly ask him what he meant, rather than making assumptions.
