Image Uploader is a client component, so almost all events are fired on the client side and can be handled in JavaScript (the additional information you can find in the Handling Upload Completion topic). You need to specify a client event handler, for example, AfterUpload event handler and do whatever you need there: trigger post back to a server, initialize AJAX request to a server and so on.

Another question is how I can get the information of the resized image such as length, width, height, etc? Thanks Lei

See reference for additional information: ImageUploader Properties (Upload Group).

I want to avoid it overwritte the existing file with same name. And how can I get the file size of thumbnail image? I found a property getUploadFileSize(Index). But not found same property of thumbnail image. Thanks Lei Edited by user Monday, October 19, 2009 4:18:40 PM(UTC) \| Reason: Not specified

File size of generated thumbnail - unfortunately you cannot know it on the client side because Image Uploader creates thumbnails asynchronously and there is no way to calculate this size in advance.
