Bulk Product Image Upload

Hi there,

In the past, I've generally used an external API through my printing company to upload images of my prints for sale on my website. I produce hundreds of products which regularly need to be added to my site (every ~2 weeks). I'm now considering how I might be able to do this upload myself without the aid of the external API. 

However, the issue I have is in associating the product image with the entry. Is anyone familiar with an easy way to host ~100 images and quickly spit out image URLs to add them to my .CSV bulk upload? Or perhaps a different solution that might achieve the same result?

Thanks!
