Browser Based Photo Uploader & Resizer

I need a web / browser based photo uploader that is similar in functionality to what [login to view URL] uses. (they are using ActiveX from Snapfish to facilitate their processing in IE and a Plugin for Firefox). Images must be resized on the PC by the application BEFORE uploading via the internet to our servers. The resizing parameters will be set by US and will not be end user configurable. There should be no leftover file/image copies that the user has to delete on their PC. This application will NOT be in Java as it is too slow. The application should use Windows calls for resizing and thumbnail creation -- so processing must be extremely fast. The application must be cross browser compatible - IE, FF, Safari. Must work on Win98, WinME, Win2000, WinXP, Vista and Mac. The application must be a small footprint memory-wise.. The end user gui should function just like the [login to view URL] gui -- allowing for the thumbnail preview/selection of multiple images, navigation, status, click to zoom image etc. This uploading functionality will be integrated with our back-end system....and developer will need to work with my team to facilitate this integration. File renaming standards will be controlled by US. Resizing parameters and naming conventions should be controlled by a settings file the application refers to........the settings/file can be different depending on where we call the uploader from within our web application. Developer MUST have demonstrated previous experience working with image uploading and resizing.
