But either way, I think you may be breaking the rules and may get a take down notice.
Haven’t had a takedown notice in 21 years. <knock on wood>
I’m wondering if “downloading” means a software download that allows you to download the images. Some of these companies used to use software like that for transferring large files before “the cloud” was more ubiquitous.
IIRC, a few years back WotC sent me some image assets and I had to download some software to get them.
