Images stopped downloading in Chrome

Search your chrome settings for multiple files. In the Privacy and Security area, in Automatic downloads, there is a setting for "Sites can ask to automatically download multiple files" or "Don't allow sites to automatically download multiple files". If it is set for the "don't allow" and you accidentally download 2 files too quickly, it will sometimes have downloads back up in a queue while waiting for you to respond to the setting in the little lock on the address bar. But if you aren't looking when it asks, it is gone before you see it and you never know why it stopped. I hope that's what happened and it works for you after changing that.
