Are attached images & files uploaded before or after the user clicks submit?

Are attached images & files uploaded before or after the user clicks submit? If after, what happens if the user closes the window before the upload is complete?

The files are uploaded after clicking submit only. After clicking on submit button is changed to 'Please wait' until the files upload is complete.

While Multiple file uploads are allowed, the files shall be stored on a temporary location while added to the form and uploads to the final location only after clicking submit.

Hope this information helps. Please let us know if you need further assistance. We will be happy to help.
