Small White or Green-veined? (1 Viewer)

My apologies in advance for such a basic question but I took this today, what I believe to be a Small White, but on checking when I got home it says that the black on the wingtip of a Small White is unbroken.

Does this mean it could be a Green-veined White? I know they are difficult to ID easily without seeing the underside, but I only managed to get this one shot before it flew off.

Thanks in advance for any help,
Adrian

Looks like a second brood male Green-veined White

Yes Green-veined White, the dark patches travel further along the outer edge (termen).

Thanks very much for the replies, it's nice to have a positive ID.
Much appreciated.
