Gallery support

Hi All, wonder if anyone can help…

Currently adding features to my blog. lewis.homeunix.org/blog

I want a photo gallery installed. Basicly the features i want are that recent and random pictures appear in the sidebar as thumbnails…

Also a gallery page… which contains albums which obvioyusly contain photos…

I want something which is reasonably easy to install though.

can anyone help? what should i use?

Lewis
