Can't read and show image

[dina]

Hello,

This is my first time using Scilab. And I have no experience at all. I'm
interested to learn Scilab, especially for image processing.

I had installed Scilab 5.3.3 and SIVP 0.5.3 on my Windows XP. My first
attempt is to read and display image of lena.png. And I followed steps
inside tutorial,but failed.Could anyone help me with this. Am I missing
something? How do I know that my installation is working well?

1st attempt:
-->im=imread('lena.png');
                      !--error 999 
imread: Can not open file lena.png.


2nd attempt:
-->im=imread('C:\Program
Files\scilab-5.3.3\contrib\SIVP_0.5.3\images\lena.png');
-->imshow(im);
           !--error 999 
Bad (1 th) index in hypermatrix extraction.  

Thank you.
