If I save a picture onto my computer that I have found through google, does this count as downloading? We only get a certain amount of space to download a month before it starts to charge extra, I don't know what could be causing me to go over other than saving pictures. But I didn't think this would count. Thanks.
Every thing you see on the internet counts as downloading. Even if you didn't save the picture, in order to view it, it would need to be downloaded (into your temp folder). So to make it clear EVERYTHING that you see, and EVERYTHING that you save counts towards your download limit.
Unless your ISP has particularly low download limits, or you are downloading huge files - like full movies or lots and lots of music - then I doubt you will get anywhere near the limit.
