jQuery Image Resize Plugin

Few days ago i wrote jQuery Plugin Tutorial, today i want to give away my first open source jQuery plugin: image resizer. I made sure that it’s compatible with all major browsers: IE6+, FF3, Opera10, Chrome (didn’t check with Safari, hope someone can do it for me).

The whole idea was to make it as simple as possible to resize image to given size.

Microsoft hacked FireFox

Well not exactly, but if you installed Service Pack 1 for .NET using Windows Update, check your FireFox addons for a plugin called .NET Framework Assistant and disable it right away. If you think about leaving it enabled then think again, this plugin does NOTHING except adding well known (IE) security holes to the FireFox. I would advice you to uninstall it but surprisingly, Microsoft removed uninstall button! Continue reading Microsoft hacked FireFox
