1) Nivo Slider: A stunning jQuery image gallery with 16 unique transition effects. Comes with many featrues and compatible with most browser versions (IE 7+, Firefox v3+, Google Chrome v4+, Safari v4+ and Opera v10+). I like this plugin and i recommend it.
2) Gloss: Gloss is not an image gallery, it’s a lightweight jQuery plugin to create a gloss effect on images for (Mouse over, Mouse out) action. (It’s also supported for IE 6+ browsers).
Multiple files can be selected, they can even be drag ‘n’ dropped from the desktop and the upload process can start automatically or with an event (like clicking the “upload” button).
A progress bar can display the status and uploads can be canceled anytime.
It is possible to use multiple instances of the plugin in the same page and jQuery File Upload is compatible with any server-side application platform.
Komodo Edit (Windows, Mac, Linux)
It has syntax coloring, folding, background syntax checking, auto-complete and calltips. It also includes libraries for autocompletion for jQuery, Ext JS, Ruby on rails and more.
I just recommend Komoodo Edit.
