Some Questions From a Newbie

Please bear with me as I am a somewhat frazzled after accidentally deleting some pictures.

Basically, I was burning pictures from my computer onto disc. The task became monotonous, and I accidentally deleted things before they were burned. As soon as I realized (which was pretty soon after - the only things I had done were moved other pictures around in files and possibly deleted a few) I did a system restore to several hours before deletion, hoping that would bring the files back (which was a stupid assumption, I know). The system restore did end up bringing back a computer game I deleted. I went online and eventually found Recuva...downloaded and installed it, and recovered thousands of files of various types, with only a basic scan. Some don't seem to work, but many do. Of course, because I stupidly recovered so many files, it is hard to know if the ones I wanted are there. I'm sorting through them now, after removing all but the jpeg, gifs, and png file types.

My questions (and I have searched and looked at the help section):

1) Would the system restore have affected the ability of Recuva to find the files I had deleted, especially because of the game was brought back?

2) Because I did very little after deleting the photos, chances are most were recovered because of less time to overwrite, am I correct?

I plan to do a deep scan later, but before I continue with that I want to make sure it's worth it.

Again, I'm sorry for the stupid questions, but I'm a bit on edge right now. I'm also not particularly computer literate, as you can probably tell.

1) Would the system restore have affected the ability of Recuva to find the files I had deleted, especially because of the game was brought back?

Running system restore was not a good idea because with all the files moved around it's highly likely clusters belonging to deleted files have been overwritten.

As for deep scan this won't help because if the files are damaged they will remain damaged, however still run Recuva and see what it finds first.
