[jQuery] jquery.form.js and uploading only files

[Rob Lacey]

Hi there,

I'm trying to use jquery.form.js to allow file uploads with my 
application. I'm trying to replace saving the whole form and uploading a 
image all at the same time by hijacking just the input[type=file] change 
event when you select a file and saving just the file using ajax and 
then the whole form can be submitted as usual without the image. 
Basically to always save the image first to avoid uploading it multiple 
times if the rest of the form data is found to be invalid.

I can get this uploading the image working fine, but by submitting the 
entire form. I want to filter down the form data conserving only the 
file upload. Can anyone point me in the right direction on how to filter 
the uploaded data?

Many thanks
