[2008] ToolStripItem Image Margin?

[Icyculyr]

Hey, I'm writing a custom class (1200 lines so far) for coloring toolstrips and they're buttons, it also works for context menu's, what I am wondering is where is the option on a toolstrip item to show an image, IE...

There's the check margin, which has a tick in it, when you set Checked = true, but I've seen ImageMargin, and an option to show that (AND, add an image to it) can anyone tell me if I'm making things up in my mind?

Because I can't find it

Cheers
