marketpress - importer; how to bulk ad image?

im using the csv importer for the marketpress full version and im successful in adding the products in, but i can't seem to find a way to add the product images in by bulk?

the example csv provided gives these column headings:

title,description,sku,price,sale_price,tags,categories,stock,external_link,download_url,sales_count,extra_shipping,weight
Product 1,Sample product description,32432432,112.04,69.99,"Tag 1, Tag 2","Cool Stuff, Red Stuff",,,,1,,
Product 2,Sample product description,321321321,0.12,,Tag 2,"Cool Stuff, Red Stuff",2,,,,3,
Product 3,Sample product description,23232,3.21,2.983,Another,Red Stuff,,,http://test.com/myfile.pdf,,,3
Product 4,Sample product description,,1123.34,,test,"Cool Stuff, Red Stuff",4,,,,2.19,
Product 5,Sample product description,657657657,15,,,Red Stuff,5,http://mytestsite.com,,3,,1.3

i've tried the img url path under the "external_link" column but that is for an external link download.

i don't see a point to a bulk uploader if i have to go in image by image just to change the 1 attribute. either way any help is much appreciated!
