I noticed that some of my photos that I downloaded from my iPhone are PNG and some are JPG.  What’s the deal? How to standardize?

All those that I set to send directly to facebook are PNG.  They are also 720 x 540 (or 540 x 720) whereas the photos kept on the camera are 2048 x 1536 (and the ones I have with a special 7 Megapixel app are 3180 x 2385!  Wicked.

Lightroom doesn’t like the PNG files.  Why?  That’s another story.

So I just wrote a quick action in Photoshop that is a “Save As” JPG.

Then I threw all my PNGs into a folder called _PNG tank and ran a batch on that folder and voila – done.
