From Shell Cottage, the trio (Harry Potter, Hermione Granger and Ron Weasley) with Griphook the Goblin are going to the Gringotts to get one of the Horcruxes which is in the vault of Bellatrix Lestrange.
With the help of Polyjuice Potion, Ron and Hermione are going to disguise (Hermione as Bellatrix). Whilst Harry going to use his Invisibility Cloak.
The first photo shows the character of Ron Weasley, played by Ruper Grint, in disguise.
While this one shows Ron inside the Gringotts Bank and bunch of goblins walking around in the background. Actually, Rupert Grint is having an interview here.
