This is a C# problem.

In any case are you creating a class/object that is based on the tabcontrol
that contains: a tabpage, a picturebox, two button?

Say you created an object based on tabControl.

This mytabcontrol object when initialized (new) will
contain or add a tabpage, a picturebox, two button.
Button 1 creates a new tabpage;
(AddEvent Handler for its function)
Button 2 deletes current tabpage;
(AddEvent Handler for its function)
picturebox will get myImage

Off to the side somewhere
Two functions
1. Event Handler function  for Button 1
2. Event Handler function  for Button 2

You want access to the tabcontrol's current tabpage (in your object there is
only one, index 0) .
Add and place Button 1 and Button 2 in nice positions on tabpage and before
you place picturebox on tabpage you insert whatever image it needs then
place it on the tabpage; this save from having to go find tabcontrol's
tabpage's picturebox.

But if you want that picturebox after it is placed on the tabpage

mytabcontrol.Item(0).Controls.Item(x) where Item(x) after iterating through
tabpage controls collection is of type pictureBox.

That is your object.

There are many ways to do this. This comes to mind. But set it up correctly
and you may never need direct access to the picturebox
