If you own the low cost photo stock script and are having trouble with the payment gateway for Paypal I have the fix to get it going. My config file was all compressed and unreadable and I could not figure out what was what. I now have the file where it is readable and it works. It will now reach Paypal with the payment details. If you are having or have had the same problem let me know. You can see my website using this program at Photo Stock R Us .com .
