WebDev: What is the best way to do a multi-file upload?

Question

I want (barely computer literate) people to easily submit a large number of files (pictures) through my web application. Is there a simple, robust, free/cheap, widely used,

Answer 1

We had a company come up with a Silverlight upload that could resize the pictures before hand so that the 5MB files didn't have to be uploaded and then resized. The image resizing capability wasn't included with the clr that comes with Silverlight. Occipital came up with their own. You can see it here: http://www.occipital.com/fjcore.html

I don't know what they would charge, but we have been extremely happy with how it works. If you don't need the resize capability before uploading then I would go with one of the flash upload options like http://swfupload.org or http://www.codeproject.com/KB/aspnet/FlashUpload.aspx
