Great plugin Alex, I’m having this same or a similar problem which may be being exacerbated by the other admin of the site being tech-naive and uploading every picture at huge sizes (one was 6k by 8k px? what the hell? so users start clicking before everything loads maybe) the solution here might help me.
But what I’m really posting for is to complain about all the jack-@$$es who b1tch that you don’t immediately (and for free) solve their problems. There is one on every thread for NextGEN. To them I say: try paying Alex if you want better support, this software comes without any guarantees, unless you pay for them, thousands of people use this plugin (for free) and Alex does an amazing job giving the support that he does. It’s open source, if it doesn’t work the way you want, you are supposed to fix it and give Alex the patch.
Sorry about the rant, maybe I’m the jerk, but it really seems to me that you go out of your way to give support to non-paying users and for that you deserve our gratitude, even if you can’t jump on every little problem.
