How to extract images from Axure project?

I have an Axure project (.rp) that contains a lot of images. I am trying to extract these images from the project so that I can use them in a website.

I noticed I can export the entire project to HTML and the images will be in folders, but the images will have effects applied to them (shadows and rounded edges) while I want to get the original images.

Is there any way to do this?
