Document viewer which shows an image of it without uploading image(thumbnail)!

Hi there, I need an image Hi, I'm looking for a document downloader for my WordPress website. My website will be about sharing and downloading worksheets of some lessons. I have gone nearly through all plugins on WordPress and couldn't find something eligible like what's on this website: [login to view URL] You must signup to the webste to see how the tool works. Do not waste your time looking for a plugin on WordPress. You won't find any. My website will be for my students and colleagues to download word or pdf documents however I need something nearly or exactly like the one on: [login to view URL] There's on important condition I need for the document downloader. The downloader must show the images of the document automatically without uploading each page (thumbnail) of the document because I will upload tons of documents so I can't take a photo of each image but instead the tool had it to display what's inside by sifting through pages so the downloader will exactly know what they are looking for. If you think you can do it pls contact me if not pls let's not waste each other's time. The thing I'm looking for must: 1 display the document and its pages --------"like the one on the above-mentioned website "[login to view URL] (you must sign up) to see how things work! 2 displays the number of downloads on the tool -------like the one on the above-mentioned website" 3 Users when clicking on the document can also download --------like the one on the above-mentioned website" 4 Users can like or dislike the document-------like the one on the above-mentioned website"! 5 Uploader/teachers/authors should be displayed "name/date/time"------like the one on the above-mentioned website"! 6 Printing symbol to download--------like the one on the above-mentioned website"! 7 Any document can be saved for the user's account to check on later---------like the one on the above-mentioned website" Thanks Mohand
