Share files between domains?

[bringsjord]

I would like to be able to retrieve files from one domain and use them in another domain within the same reseller account. I've tried this:

<img src="/home/myAcctName/domains/domainA.com/public_html/pic.gif">

executed in a page on domainB under the same reseller. No picture.

I changed the CHMOD of pic.gif to 777, but still no dice.

Is this possible to do? If so how?

Or should I just use "http://www.domainA.com/pic.gif"? I know that would work, I just thought this might be more efficient.
