Remove Images from Main Page

Hi,

I just wanted to know if it is possible to stop displaying the images on homepage in wordpress. I wanted to do this because i have installed a plugin which generates thumbnails of images. These thumbnails are shown on homepage and later when the person clicks the post the real image is shown.

But unfortunately since im not able to stop the full size post images on homepage, both full size as well as the thumbnail image are appearing.
plugin tat i use http://www.alakhnor.com/post-thumb/?page_id=2
