Hi Esam,
If I understand you correctly, you want to preserve the image data
even if the user used an invalid value in another form field,
rendering the form invalid?
You could:
1. add the image to the user's session, without saving it to the DB.
2. add the image URL to the user's session, showing a thumb it in the
form using the URL.
3. first validate the form, then download the image, preserving the
location of the image in the form field until the form validates
(4. retrieve the image using an AJAX call over the server, before the
form even gets sent
This is how Google Contacts does it. But I consider this option not
within the scope of your question.)
I would first try 3. since that is the easiest. Then to improve the
user experience, I would probably switch to 2.
And if I have time left, I would implement 1.
Good luck! RR
