So I have an .dll file which I know is written in C#. 

I used JetBrains *dotPeek*, to decompile the .exe and inside the .exe I can see a folder called **Images** and then inside that folder around 10 images some of which **I would like to change**. 

I understand that dotPeek is just for decompiling I think. So after googling this I came across two programs, *Resouce Hacker* and *ResTuner*, which both said they could edit images inside a dll file. So I opened this dll file up in both and in both programs all it showed was one folder called "Version Info" 

Is there a different program which can do this?
