I have a site that allows people to upload powerpoint/PDF files, but when I show them a list of powerpoint & PDF files to download, I want to give them a small picture of what the first powerpoint slide/PDF page looks like. I have seen sites that do this, but I do not know what code to use.
I am using JSP and an Oracle Db.
Can anyone give me some code that will show the first page of the file they are about to download? They basically just need to know if they already have this one or not, so I need to show them a thumbnail of what the doc looks like.
