How to output information with three states by pictures

Hello, all,

I have three state of current: hi, middle, low and I want to
output it by three different pictures (png) in the middle of the screen.

It possible to use the “pic x,y,image_id” instruction.
But than I chenge the pages of the screen this information
disappear (of course).

Is it possible to solve this task when three pictures should be displayed at the same place on the screen by Nextion’s instructions ?

Thank you in advance.

hold your picture image number in GLOBAL variable then on the page initialisation enter p0.pic=va0.val (using your names of course).
