peeps, i am trying to put an image on the form without using the background property nor using a picturebox. i got this problem solved by using the form onpaint overrides. the problem is, i need to change that image when i click on the form as well as when i click a button. any suggestions. this is what i have so far. (just add in any of you images instead). also, i am confused if i should use the base class click or the overridable onclick event
