[Plugin: NextGEN Gallery] How to insert a gallery at once ?

Hi everyone,

I’m running wp 2.7 and the last NextGen plugin.
But I don’t understand how to insert a complete images gallery at once. I mean, before, one just has to upload the images via the nextgen panel and to insert the gallery ID in the post.

Now, when I insert the gallery ID in the post it doesn’t work. Ok
I’ve searched and found a solution : to click on the insert button in the article/page creation page. Ok
A popup is opening. When I go onto the nextGen menu, I select my gallery and can see my images. The only choice I have is to insert them one by one and furthermore, it generates some html tags in the article.

How can I insert all my images from a specific category at once ?
