I just want to sing a praise for the Resources Tab in Stud_PE. It helped me with an unpacked upx which Resource Hacker was not able to analyze.
I realized that if we want to take a look into the resources, it's recommended using more than one tool, because when Exescope doesn't see a thing, maybe ResHack can help us or ever some other ones...
One more thing: these tools look into the resources section and can show us images like bitmaps that were compiled being RES files, isn't it?

So my question is: What about that images that no resource editor "sees" but that lies inside the exe in its original form: for example, here we have the beginning of a BITMAP whose size is: 4EF6h. If we take HexWorkshop, we copy 4ef6h bytes (look that F6 4E after the BM header) and paste it in image.bmp, we'll be get the original image.
