If I'm not mistaken, what you're asking for is not yet relevant to the list yet. I think you need to consider the business logic (site navigation, UI - layout and all, functionalities/features/purpose of the site, etc) before you begin coding... as this will save headaches to come. Here's my question your intention... do you want the user to waste his/her time trying to upload an image to a temporary location on your server (not mention waste of bandwith and server processing) before the user has the final decision whether (50%/50%) whether to keep the picture or not??? Shouldn't the user DECIDE that in the first before clicking browse (form/ajax) > submit/upload ??? OTOH, if you want to permit the user to upload as many pictures as he/she wants, then selecting only the images the user likes best at a certain point later in time w/o having to upload.... then that's a another matter.
This is what I mean by you need evaluate the functions/features of your site. After you figure out the 1st step, then deal with storage mechanisms (DB / Filesystems) for the pictures. Then comes coding / site layout design.... w/o clear understanding of the 1st 2... your coding will have unnecessary steps/codes, not to mention your current hurdle... After you figure out the details of what you want your site to be/have/offer, then try to learn more in details about the technology you want to use. If you then you try to implement something but fails, you should try to troubleshoot/debug 1st and research as much as you can before asking. All of this you're asking for 95% available on web... Just spend time to read it. You should first learn as much as you can about what you want to use, in this case Struts, before asking very basic question like "picture upload"... There many ways to implement this. Old school basic html form/post... new school
ajax... another method to use is java applets... the list goes on... :)

I suggest you take a look at youtube.com's file upload. Perhaps you might
want to consider implementing something similar to theirs but not as advanced?
I haven't looked at AJAX in depth very much yet but if you implement simultaneous
uploads, you'll have to use threads. You'll have to look at the Commons' FileUpload.
That library is the best and probably the only for file upload there is. Like I said
before, most of what you're asking is there on the internet. Just google for
'ajax file upload'. After seeing some samples and various methods, you decide
to implement your own but run into problems where you can't find the solution,
then I'm sure the list is more than happy to help you fix if it deals with Struts.
Someone has suggest you to look at jquery plugin. That may work or may not
work for you. That's why I suggest you read and find the options available
and choose what you like. One of the many things I like about Java is you have
more than one way to do something to reach your goal.
Regards,
Tommy

Hi Tommy,
Thanks for your reply. I thought I would get the answer very quickly if I
post the answer on this form after struggling for a week.This is very
general question thats why I did not mention all the requirement. I am
working for an insurance company. And we have existing framework of
Sturts+Spring+Hibernate. And the requirement which I am working on is that
the person who wants to buy the car insurance he has the option to upload
the four pictures of his car.Along with some other details.After selecting
the picture he would like to see which picture he uploaded. He cannot delete
the uploaded picture but at least he should be able to see those four
pictures on the jsp page. He can upload png,jpg or gif files.At the bottom
there is a continue button after continue I have to save those pics into the
database.
Let me know if you have any questions.Thanks for your efforts and help in
advance.
