How to add new pngs for treeview?

[origel]

I want add a treeview widget. This widget will use some png images for UI display. I will add pngs resources to project firist. I have read the code pngs.v, this code is gen by command line. v bin2v images/check.png images/circle.png images/selected_radio.png -p bytes_ -m ui

If I want re-generate this file, I need those files images/check.png images/circle.png and images/selected_radio.png. Can you upload those files? thanks!
