Best way to hang pictures

What's the best way to hang pictures on apartment walls without leaving a lot of marks? The tenant before me used tacks and they left SUPER tiny holes - but the apartment still charged him an insane amount. The landlord warned me.

So what's the best way to hang pictures that can easy be fixed/patched before moving out?

You can patch even a nail hole, I think the person before you was just lazy about it. So just don�ft forget and you should be fine.

Google gives you tons of ideas and items on "how to hang pictures in apartments".

But if your landlords warned you, you should discuss in details with the landlord. Otherwise, have you thought about putting your pictures in a big frame and placing it on the floor leaning it against a wall? Very stylish!

Unusually, my apartment actually has a picture rail, however . . .

Have you searched for removable sticky hooks - there are some products (I think from 3M) that stick on and can then be removed without marks.
