While you work out the photo thing, yes, your cham will probably become used to you. It really won't "like" you, but will recognize you as a food provider. Yours looks young. They're more skittish when they're young becuase they basically think you're going to eat them. You're a predator and they're prey. They run, hide, or hiss and get defensive/aggressive.
Veileds are notoriously more aggressive. Females are generally less so, though. They all have their own personalities and moods, just like people.
So yes, EVENTUALLY, she will get used to you. You'll be able to handle her. She won't like it, but you can do it when you have to. She may even calm down enough with age that she will climb onto you when you put your hand in her cage. But at this age, she's scared to death that you're going to eat her.
