Look within the various categories of files that are here:

I think they're very handy - especially, that quite a bit of them are .svg files, so you can adjust the size of the image and it doesn't look distorted, so you can use it for any size! Although there's still many .png images.
They might come handy - so I just thought I'd throw that out there.
