    Rotation Thread
Click For Summary
Users are experiencing issues with photographs taken on cell phones appearing rotated when uploaded to PhysicsForums. The problem seems to stem from the metadata associated with the images, specifically the orientation tags that different software interprets inconsistently. Suggestions to resolve the issue include editing the images by cropping or resizing them, which forces a new save and may correct the orientation. Some users have reported that this issue may have arisen after a recent Android update, affecting how images are processed. Overall, the discussion highlights the need for users to adjust their image files before uploading to avoid orientation problems.

Ok, I’ll bite…. Many airworthy B-25 survivors, but which one was this and where did you see it?
I live in Hamilton ON a few miles from the warplane museum.
They have a PBY Catalina/Canso, a Mitchell, a Douglas C-47 and an Avro Lanc. All airworthy. They run flights every day and fly over my house daily. Never get anything done around here cuz I'l always lookin' up!

Some day soon I'm gonna book a flight.

[ UPDATE ] I downloaded your pics. I am unable to rotate them in a pic viewer, in fact I am unable to even open them in Photoshop.
I downloaded the first one to my iPad and opened it with no problems in Photoshop. It was in its rotated orientation.

In addition to the suggestion of cropping the image slightly (or not so slightly) to force saving a new version before posting, simply resizing (resampling) it might also do the trick. Make the new width maximum 800 pixels and the new height maximum 620 pixels. The forum software resizes larger images to those maxima anyway.

An image that is rotated is not always saved rotated. Sometimes a program only modifies the orientation EXIF tag.

I downloaded your image - which was sideways once downloaded - and opened it in Shotwell, allowing me to easily rotate it. Here is that newly saved image:

page 96 of plumbing book.jpg


But the program only modifies the Orientation tag. If your web browser (or any other program) does not consider the Orientation tag, you would see it sideways; if it does, it is in the upright position. (With my browser - Firefox - it is in the upright position.) EDIT: Now that I posted the reply, the image has gone back to its original orientation, sideways! PF most likely did not consider the orientation tag when saving it.

The thumbnail of this same image - anyway on my browser - is still sideways. I inserted it at the end of this text for you (via PF, not another image uploaded). If you click on it, it should open in the correct upright position (as the one above, that is).

How do I know for sure? When I open the image I modified with Shotwell in GIMP, the program asks me this first:

GIMP-orientation-tag.png

This image contains Exif orientation metadata. Would you like to rotate the image?

My guess is that either a program along the way (your camera taking the picture or your gallery on your laptop) includes a wrong Orientation tag, or another one ignores one already included.

Considering I am now having the same problem with pics from my own phone, I am beginning to suspect this is a bug introduced in a recent Android update.

Well, at least your pictures are not posting upside-down, like in this thread... o0)

Yes, sorry, not sure why that happened.

I-Phone to One drive. Open viewer, take a snip of the picture...How I'm skirting it is by using the snipping tool.
