What is the daily limit on the number of images that could be processed using Watson Visual Recognition. Free plan on the doc shows 250. Can we upload more on a Standard plan ??
Standard plan will allow you to upload more then the free version of 250.
Just be aware that training events are the most expensive. So try to batch upload with zips.
With the standard plan by default you can process 25,000 events per day. If you would like to do more you can submit a bluemix support request asking for that to be lifted.
