After some assistance (paid) to complete some code

It looks as though you need some arrays set up to point to your different images.

I would suggest using arrays of structs that holds all the display parameters,
which seem to be fixed for each bitmap.
An enum could be used for the indices.
A display method of the struct would shrink down the code considerably,
and you can simply select and display.
I miss the information, which destinations are sub-destination of which final destination.
