VB6 Excel Add in - Pictureboxes

This may sound like a newbie question (because I am one) but I have code in VB6 to draw on a picturebox with a mouse click. I would like to add this to an excel add-in . The probelm is picturebox is not in excel (from what I know and researched). I've read about using excel.shapes but I am looking for people's opinion or suggestions on what the best option would be to replace picturebox.

Thanks,
JO

Maybe not quite the same as a PictureBox but UserForm, CommandButton, Image and Frame Controls all have Picture properties.
