I am selling a product with these images. this would most likely be a one time activity. I run on nice spec dedicated servers with already tens of thousands of images in wp-uploads, so from front end performance will not be an issue. only the painful part of adding so many images in small batches.
Is there any option of uploading them via FTP and then executing a set of mySQl scripts? Also, would your premium version offer more agility in uploading my images?
