I don't write reviews very often, but this developer deserves a praise. I was looking for a plugin to replace SigPro for ages now. K2 Multiple images plugin does exactly what I need. You can upload images one by one, instead of zip file. It's good if you have loads of users on your site, because you don't need to explain them how zip images and what to do next. Regular users just want to add images by a click of a button. And this plugin basically does that.
I was impressed how quickly developer replied to my email with customization. Emailed him at midnight, received answer early in the morning.
Simply brilliant work!
