Uhm, the PHP code runs on the server side. So unless you want to capture
screen shots on the server PHP has nothing to offer. You'd need to look at
ECMAScript applications that may do the trick on the client side. But then
again, capturing a screen shot is fairly easy on most systems (the most
difficult, but also most flexible IMHO being OS X) and uploading the resulting
file isn't that tricky either.
There are two ways you can deal with image files and a database. You can crate
a BLOB field and store the binary data in there, which bloats the db size, but
keeps everything in one package. Or you can store the images on the file
system and only store a reference in the database. While that is much leaner
in regards to db size it comes with other problems, such as missing files and
the difficulty in changing the storage location of the images.
In my (still not done after 3 years) PiViViewer application I use the second
approach as I rather work with the disadvantages than be tied to the database
and an application to retrieve the images.
