Question on Transloading from another web page.

Using "Add Items >> From Web Page" I see you can scrape every image from a web page by adding the page URL or you can transload a single image by adding the individual image URL in the field. The problem with scraping the page is that you get all of the graphics, icons, ads, smilies and everything else that is an image, not just the desirable images. The option is to transload each desirable image individually.

How would one go about adding more fields so that you can select and transload 5, 10, 15 or more images at once?

Personally I would drag the items I wanted from a webpage to my desktop, zip them (maybe) and upload them from there. Be aware you should have permission from the copyright holder to load images from elsewhere on the web to your website.
