Use external links for images

I had importeed over 1000 products, after a few days now the images are all gone, so ive removed the products,and importing with the “Use external links for images” option not selected.

Now all the images in the “Import description images” field isnt showing the images.

So what do I need to do to show all the images, for 1000 products, without killing the buget for hosting 🙂
