I have to disagree with sgt1372 above on one thing- taking group pictures of the knives (like 10 in a single pic) can allow identification depending on the knives, the quality of the pictures, and the knowledge of the people viewing the pictures.
Group pics will save the OP a lot of time and effort. And showing group pics is a good first step to let her know what type of knives she has, like if they are quality, or if they are cheap junk. And if there appears to be any gems amid the clutter, she could always go back and take better, individual pics of those. Pocket knives can be small, and several can easily fit into a single picture and still be identified.
She says that she doesn't have the emotional energy to sell them one by one, so she might not be willing to put the time and effort into photographing them one by one, and then going through the effort of posting all of those individual pictures.
I've taken a lot of knife pics, and posted a lot of pictures of knives on this forum using Imgur, and it can be quite a bit of work (stage knives, provide good lighting, take a decent pic, upload pics into computer, upload pics into imgur account, post pics into Bladeforums post). That can be a lot of work if you're photographing an entire collection. And it can take an emotional toll if we're talking about a woman going through her recently deceased husbands belongings.
I say- start with just a a few group pictures, and we can go from there. Group pictures might be enough.
