When commenting on how someone looks in a specific context (like a photo or an outfit), use 'estar'. 'Es guapo' describes them in general.

Frequently Asked Questions
Is the 'permanent vs temporary' rule good enough?
It's a great starting point, but it can be misleading. For example, 'estar muerto' (to be dead) is permanent, but uses 'estar'. It's better to think of 'ser' for identity/essence and 'estar' for state/condition.
Do all adjectives work with both ser and estar?
No. Some adjectives almost always go with one or the other. For example, 'es posible' (it's possible) is an inherent quality, while 'estoy contento' (I'm happy) is a state. However, many of the most common adjectives can be used with both to show different meanings.
