Distorted Image Created with PDFCreator

Every time I use the program to create a PDF file of a certain bitmap image, it appears distorted in Adobe Reader 10 unlike the other PDF images I created with the same program. When I used other programs to create PDF files based on the same image, the image did not appear distorted in Adobe Reader 10. What could be the problem with PDFCreator and what should I do? 

I'm still waiting for help.
