Culture

Hello, please help me this is driving me nuts. So I have this Mugeners 3 screenpack made for low requirements and I want to add my custom sprites. So I do everything step by step, there is pdf file, I customize it in photoshop, open Fighter Factory do everything what is needed to do and nothing, the portraits are not showing up, it has been replaced because the original picture the character had is gone, but the new portrait is not showing up either. Can you help me?
