Take a look at the export and import csv option. If you take you current shop and export as csv you can add the additional products by adding lines to the csv file. You'll be able to copy the image location so it uses the same one. To get it into the correct format export your shop first as csv. Now open that file in your favorite csv editor and setup your additional products using the same format you already see being used in the csv file.

ok I'll try that, my program just froze and I lost an hour of work, ugh. I hope that works thank you.
