Remove timthumb from theme?

I’ve read a few posts about removing timthumb but they’re all workarounds for using timthumb. I don’t want it anymore. All of the posts I’ve seen in the forum have been closed too. Considering the number of sites affected by this vulnerability, I’m surprised.

I know there’s an update and I’ve updated my script, but I would prefer to let wordpress resize my images. Anyone have any ideas?

Thanks…
