[pstricks] Fractals-Ex1.tex

[Chris Sangwin]

I have looked at the fractals examples in the file Fractals-Ex1.tex 

I would like to use these images, in a file which also requires the
packages

\usepackage{graphicx,epsfig}

However, including either of these two packages causes an error

"!Illegal unit of measure (pt instead)...."

Does anyone have any suggestions how to avoid this problem?

Thanks
Chris
