Muslims:would this be considered haram?

[Heba]

So i have an Islamic instagram page. For those of you who don't know, on instagram you post pictures. So most of my pictures that I post I take from someone else's account. Ex: if someone posts something islamic, I might take it and post it, without giving them credit. Would it be haram to do that without asking them or giving them credit? The thing is, the same Islamic picture is seen on more than one different account. Like I might have seen a certain Islamic picture posted like 10 times.

So would it be haram? And what if that account hadn't taken the picture from someone else but made it themselves, would it be haram?
Jazak Allah

Yeah because they had instagram in mind when they made these rules up LOL.
