Referencing several images

Hello, I have a problem regarding referencing images in UI. For example- I have several images in my UI and I want them to move along the y axis as they get input via bluetooth. I know how to change their rect transform but I don't know how to reference different images. For example(just a small part of the code): public static object[] arrT; public Image zero = ... //this is where I do not know what to use public Image one =... //same as above void moveT() { %|629584269_1|% %|-1072288969_2|% }
