My page is marked as lack of effort and may be deleted

It's not that I'm being lazy I just couldn't continue because the help page is incomplete . . .

I can't get the screen shots myself so does anyone know of any good places to search for images?

Also, I only have a basic knowledge of firearms but I assumed that if I got the images and put what I think it is, someone with more knowledge would just be able to clarify and edit (if needed) for corrections/ additional information. Will it just get flagged as incorrect and nominated for deletion?
