I am familiar with Nivo and like that slider, I will check out the blueberry one as I am not yet familiar with it.
NextGen gallery looks great and I see it one of the most popular ones out there. I came across another today that caught my eye, EasyRotator and I think I will be trying to integrate that one first.
I was able to get meteor slider to replace the custom header image with conditional statements in the header.php file in the theme and with a few extra lines of css to resolve layout glitches, it seems to be working quite well. its a little confusing though as I need multiple slideshows and there is a few things that I dont understand. However, the plugin developer is VERY active in the support forums, so thats a major plus. I figure I will be asking a few more questions in there I think as I work in sliders on more pages but I made good progress today!
