It could be even better, if it would be possible to upload more then one image in one step. But so far: good work! This extension makes sence, even in this "sea of galeries". Thumbs up!
You can upload as many images at once as you like. Just use a browser which is capable doing this. Internet Explorer is out of the race but Firefox and Chrome can do it.
You can find a video demonstration this functionality in the manual:
If they improve the support, this could be a great gallery, but for now only "Average" because I can not use it and no one answers the support mails.
I had a small problem with this menu (it was my fault) and I found out that pulse has one of the fastest and friendliest supports I ever wrote with!
For me it is totally ok to pay for an extension when it works like this.
