They have turned off uploading again this weekend. I have to admit, I'm starting to get a bit annoyed. They keep promising they won't have to do this anymore, and that they have hired more reviewers.
The problem is my workload generally dictates that I shoot on the weekend, and upload to all sites Sunday night. BigStock is too often blocking uploads at this time, so I have to remember to get back to them later in the week. Lately, I've been forgetting or simply not bothering.
