Learn how to create a standalone application for uploading images to your website. This application uses an "iframe" to achieve an AJAX-like method for easily uploading multiple images to your server without the need for an FTP client. Images are automatically uploaded one at a time and displayed as thumbnails so you can keep track of which ones have already been uploaded. This tutorial is an enhanced version of Asynchronous image file upload without AJAX by Martin Konicek. The enhancements include being able to preview "gif" and "png" images in addition to "jpg" images, notification if the image already exists, an error message in case the upload fails, and image size restrictions.

There are a number of tutorials on the internet that teach you how to create colored boxes with rounded corners. Many of these require the use of Javascript which unnecessarily bloats your HTML code. Some, such as this one, use only CSS and HTML to create this rounded effect. A few even show you how to create these rounded corner boxes with fluid, changing widths. However, none of them that I know of teach you how to do all the above, add borders to the boxes, and use multiple background colors. None, of course, except this one.
