jQuery is not only a fairly easy javascript language to work with, it is also, when in packaged in a plugin, very easy to install on any web page, making them perfect for non-developers as well. Image galleries/sliders, without the spice of js, tend to be bland and featureless. Throw in a little jQuery and you can have a easily customizable feature-rich image gallery that will present your images professionally and beautifully.
