Image Gallery Plugin Suggestions?

Hi there,
I’m looking for suggestions for good Image Gallery plugins – preferably from folks with first hand experience.

I have two seperate requirements, for two seperate sites – so seperate solutions is fine ??

1) A plugin which would nicely handle multiple images in one post. For example, write a post, upload 5 images & insert image thumbnails into post. Plugin would then handle a pop up page (preferably accessible friendly) which would show the image AND allow browsing to the other images. Rather than simply going directly to the image.

2) A plugin which allows you to set up a page which acts as an image gallery – preferably with albums etc…

I know these may be tall orders, but it’s always worth asking, I know people are constantly developing interesting stuff out there!

The above requirements are fairly loose… all suggestions welcomed!

Many many thanks,
Frank
