Automating image resizing to various sizes?

  • I have a promotional image I want to make into various sizes. Like typical phone sizes and desktop backgrounds. I will probably be doing this a lot.

    Does CSP already have an export for this? Or should I automate it?

    I think something like, opens image in 5 more tabs and sets each one to a specific canvas size. Then I could check each one and center the picture different.

    Thanks for any advice.
