Bloggers Toolkit: QuickThumbnail the online photo resizer
QuickThumbnail is an essential tool for any blogger on the go. This free service gives anyone the ability to upload an image and resize, then download the resulting file, all without an image editing program. You can resize based on a percentage of the original image’s size, or by a set of “standard” sizes, for example 100×75 for an avatar, or 468×60 for a web banner.
So, when you don’t have Image Well at your disposal, this will do the trick.
