This application demonstrates how to organize robust upload using Image Uploader. In this demo application Image Uploader computes MD5 and SHA1 hash values for each uploaded file and sends them to the server. The server script calculates hash value for the file it receives and then compares result with uploaded hash. This way you can verify whether the file was corrupted during upload.

Additionally in this application you can see how to:

• Use custom-drawn buttons in Image Uploader.
• Resume upload automatically when connection breaks.
