I hope I am posting this question to the right forum!!!

I have just completed my help sustem and compiled it.  The .chm file runs 
OK on my local machine, but when I invoke the .chm file on the web in an 
htm page from an href:
<a href="myhelp.chm"><img src="help.jpg" width="20" height="20" 
border="0"></a>

It asks me to download the file. I want it to work as web based help and 
not have to download it. The main objective is to have my users access the 
nice hierarchical contents to find a topic.  The contents panel does not 
show up in the html help topics files, only in the complied .chm version.

Question:
How do I cause the .chm file to execute on the web interactively like it 
does on my local machine without downloading the whole file?  

Thanks for any help on this....
