LOST IN CODE

I'm trying to get OSC to pull product images from an external URL instead of catalogs/admin folder.
I have received some instructions from a person on the OSC forms. But since I'm a newbie, I have been having serious difficulty deciphering his instructions however I think I'm half way there.

His instructions are as follows:

"Add in an extra field in the proeduct screen in admin. Call it "external image".
Recode tep_image function to show external image is the field is not null, or use normal image if it is null."


So far I have added the field (external_image) with in My php Amin via cPanel.
I also created the same field with in OSC New Products admin.
Now I'm having trouble with the second half. "recoding tep_image function". I think I have located the correct file (html_output.php) please see attached code. I'm lost as to what line in the code and exactly how to change it. I don't even know if this will give me the desired results. I have not been having any luck getting any help on the osc forms so if anyone can point me in the right direction, I would owe you one...a big one.

Regards
