Lua crosshair

Hi guys, I was wondering how would you draw an image to the center of your screen? Sorry, noob at lua.

surface.DrawLine in hook HUDPaint

What do you mean by image?
Do you mean lines or an actual picture of a crosshair?
Are you using custom materials?

If you want to do something like the standard crosshair (four simple dots), use surface.drawline, like Noi said. If you have a custom image for it, use surface.DrawTexturedRect. Both in a hudpaint hook.
