Web Controls and Relative Paths

[RSH]

Hi,

I'm pretty new to ASP .Net. I have discovered the usefulness of web
controls. I have made a simple web control that is basically acting like a
dynamic include file. I have defined a couple properties that show and hide
panels in the design layer based on the how the properties are being set
from the Parent page.

The only issue I have left to tackle is that some of the pages exist in the
root directory, and some exist in sub directories. The images folder exists
on the root directory. The issue is that because the parent page in some
situations exist in different directories how do I specify to the image
paths?

Example:
When the parent page is located in the root directory:
img src="Images/header_leftcnr.gif" width="19" align="left" border="0"

When the parent page is located in sub directory:
img src="../Images/header_leftcnr.gif" width="19" align="left" border="0"

Is there a way to dynamically set the path to the images in code at the time
of page_load?

Thanks,
Ron
