I am uploading images after zipping them using plugin Simple Image Gallery for k2 gallery. But the problem is the images if are too biz with height or width the lightbox goes out of the screen...

Is there a way to limit the size of images irrespective what is uploaded ???

I hope i am clear. I have uploaded few images which originaly were more than 2000px height and width 3000px. so is there a way to fix the images so that it can be seen properly...
