How do I flag a pending image

I've been wondering how do I report an image that is still pending on approval? I'm asking this because someone just uploaded seven images of Lola and Lana Loud that look WAY too realistic. I can't even tell if these are real children or not but they look like they are.

Someone please delete these immediately.

They are just meh 3D ghraphics. Not even good ones.

Edit: the dress even clip though the leg! I don't see how one would confuse those with real photos.

I don't think that is currently possible. However, if it's in pending a moderator will probably notice soon enough.
