You're not actually uploading the images from the spreadsheet, you're just telling the program where to find those images already on the server. You would need to upload all of the images manually (through FTP usually) and then put the full filepath of each image in the spreadsheet for it's product.
Thanks, both of you. Andy, I noticed 2 different images folders in the FTP. Does it matter which one I transfer to? Can I put 2000 images in one folder and then transfer? With that extra folder will the program be able to find it?
What were the paths of those image folders? I ended up modifying my source so that it would grab images with matching SKUs in the filename because I didn't feel like typing them all out in the spreadsheet so my knowledge of the default process kind of ends with the basics.
