VB.Net buttons don't show images during runtime?

Hi,

i am setting button's image property to an image from resource folder. the button shows the image in design view, but when i run the application then it doesn't.

I created new form in the same solution and assign image to a button, again it shows the image in design view but not at run time.

However if i create a  new solution then it is working fine.

i don't know what would be the problem. i rebuild the project, deleted the resource folder and then recreate. but no solution.
