Hi, I've been using NextGen Gallery for many years now, and I have never had a problem with it, it's a fantastic plug-in!
Sadly, with recent updates, I noticed that flash enabled uploads give me this strange glitch: it always uploads more images than the ones I selected. I am not sure why this is happening.
Today for example, I just uploaded one picture. The upload bar reached 100% without any problems, but when the page refreshes, I see it uploaded 4 more pictures I didn't choose! It's a hassle, because I gotta delete them manually. The plug-in certainly picked them from the folder where I store these pics for uploading. I have no problems with the other kind of upload though...
Any ideas what is causing this?
