How much does table image and psychology factor into your decisions ?

[Scorpion Girl]

How much does table image and psychology factor into your decisions when you're playing - do you actively work to create a certain perception of yourself as tight, loose, aggressive, or passive? Or do you just focus on playing fundamentally solid poker and let opponents form whatever impression they want? I'm curious if you ever intentionally show bluffs or make unconventional plays early on to set up bigger moves later, or if that feels too risky and manipulative. And does your approach change depending on whether you're playing against regulars who know your style versus random players who have no read on you?
