IPB Theme Images

[Christopher]

I'm trying to convert a IPB theme to mybb. Could someone explain how the images work in IPB? I just have a xml file that has a bunch code for the images (See sample below). How do I convert that all to images? Thanks!

Sample:

<filename>40opacity-black.png</filename>

Forget this. I'm just going to ask someone to convert a skin for me.
