Can't save rotated image without flattening first.

I have a bunch of jpeg images where I have to rotate them to correct the horizon line and then crop and re-save them. When I press apple-S to save the images I'm told that I have to save it in a different format. I found that even though the layers palette shows only one layer, the image has to be flattened before I can use apple-S to save it.

I don't recall seeing this type of behavior before. It's kind of a pain in the backside

When you rotate the canvas using the crop tool with "delete cropped pixels" unchecked it creates a new layer so that it can maintain the extra pixels that are outside the frame. Maybe that's what you're having problems with?

Yes, it's been like that since Photoshop 3.0.

If you're saving back to JPEG, the Layers Panel must show a Background (and, of course, no Alpha Channels, but Paths are supported by JPEG so those should be fine).

With JPEGs, sometimes I start with duplicating the Background with command j, making the edits on the new layer, then using Command E to merge back to the Background (sometimes the Background needs to be filled in some way to hide the original), and then command s.

You could also record an action to do Layer > Flatten and then File > Save.

I've been using the ruler tool to draw a line across the horizon and then 'straighten image' to rotate the image. I found that if I just eyeball the rotation using the transform tool this problem does not come up.

Thanks for the feedback.

I use Straighten  with Content Aware fill and I just eyeball the horizontal or vertical line using a visual choice the looks OK to me.    I get fooled sometimes by choosing a mast on a boat that isn't actually straight up and down... Works for what my needs have been; what throws things off for me is when there is a curving receding coastline that draws the eye to make it feel out of  level when the image really isn't. I am not selling images to businesses anyway!

BTW: you are way behind on version updates...
