how can we tel how many times the pdf is being opened(viewed)? - not Downloaded from a site, but opened some sort of image counter enbedded in the ebook? Is there any free hosting service which provides these image counters for ebooks? (I dont mean how can we count the amount of times a PDF is 'downloaded' from a server,- or how many times the pdf has been downloaded from a webpage,) but how many times a pdf has been 'opened' /viewed Some sort of image counter/when the image is loaded live from wherever it is hosted, it shows as a count ? ie- if the ebook is opened 8 times- in 8 separate IP addresses, the image will be shown 8 times, showing that the ebook has been viewed 8 times. I have posted this in the hosting category, aswel, as it is also a hosting question.
