Review for Save Images by Jon Jasper
Rated 4 out of 5 stars
I've had a few minor issues with version 0.5.1 starting back in FFX version 2.0.0.12, upgrading to 3.x hasn't resolved it. Images all open in one tab, but not all write to my chosen directory. I found that Add-on DownloadThemAll! works in tandem with S.I. to reliably resolve that issue.
If I launch DownloadThemAll from S.I.'s Save Images tab, I successfully get every image.
