All I do is select images mostly from Google. The fact that I post so many probably makes it seem that too many of mine aren't visible here. Given an hypothetical rate of 90% success, if you post 10 and one doesn't work correctly you've posted one "bad" one, while if I post 250 we can expect 25 not to work, and 25 is a lot more than one.That comes without saying... They are compatible to every computersystem. You on the other hand.........
