I ran the bulk

Hi

I ran the bulk smush pro through last night. When I woke I have found numerous woo commerce product gallery images missing. Per product I have 5-10 extra images. Most are still there, but unfortunately on some products, the images are broken and not displaying.

Before I manually re-upload them, is there anything I may have missed?

edit - I have noticed that all the images that are now blank/broken were pngs that are now jpgs.

Is there a way to restore the pngs? As the jpgs are now blank/display nothing
