Pixelatte_quadrats from different inputs randomly generated one picture

Hello there.
I did the video from Bhagata its in youtube called “pixelatte in touchdesigner” von paketa and it nearly looks like what i`d like to get as the final output the only difference I´d like to do is that i don´t want to have the noise on one picture, I´d like to have the different quadrats filled with quadrats from different pictures. so I tried to use one noise for one picture and put it together after it but than the noises where no quadrats more …

someone an idea?
