363313 Multiple File Upload

I need a multiple file upload script developed. I currently have a simple PHP single file upload script that, if possible, could be updated. I would like AJAX used in it for the progress bar and any other parts that it would work well with. I need the user to be able to select multiple files upon clicking the "Browse" button. Upon selecting the files and the user clicks "Open," the files they selected will be displayed to them in text form (ex. [login to view URL]). There should be an option to cancel a selected file. There should also be a "Cancel All" button. Finally an "Upload" button should upload all files they have selected with a progress bar below each file. I would like it to rename the files somehow so it is impossible to upload a file with the same name as another. I would like it to be very similar to this script: [login to view URL] but I would like it to output a direct link to the file (ex. [login to view URL]) and the ability to edit the code to add a textbox for an html, bbcode, link back, ect selectable code. Also I would like to be able to control what file types are allowed to be uploaded. I know this sounds like I need it to be very very specific, but I have a picture in my head of what it needs to look like and I would like it to look very similar to that so I gave the best description I could. Any questions please don't hesitate to PM me.
