You need to really download them and view them in the gimp and examine
the exif because on the original images coming out of the camera, SOME
applications, like new firefox, read the camera's orientation data
and display accordingly.  Some applications do not.  The solution is 
to actually rotate the actual image.

Actually, if I was going to modernize this, there would be 2 options,
one to just rotate by chaning the exif data, and one to physically
rotate the image.


Thanks for the additional information (this message and the other
message).   I actually DID download both images and I opened them in
GIMP 2.10.20 on Ubuntu 20.04 Linux.  I opened the original image in
Firefox and it was rotated by 90-degress counter-clockwise, so it
appeared like this:

Of course, my highlighting in red didn't appear.  :)    So, then I
opened the original photo in GIMP and I was asked if I wanted to rotate
the photo or not, as shown here:

When I opened the rotated photo you posted the link to, the "After"
photo, GIMP prompted me to rotate the photo, as shown here:

Are you getting the same prompts from GIMP, when you open the photos? 
If so, which option do you choose?

Anyway, when I open the original photo in GIMP and choose "rotate", I
made NO other changes and simply exported the rotated image.  Then, I
opened that image in Firefox and it appeared correct:

I haven't touched ANY EXIF settings at all and when exporting from GIMP,
I used the export defaults, for JPEG, which included EXIF, XMP, and IPTC
information being saved with the file.  I think I understand your issue
with the image getting rotated unexpectedly, but I'm not necessarily
sure GIMP is at fault, at least not based on the steps I followed.

When you load the images, are you getting different results?  Which
version of GIMP are you using and on which operating system?

Thanks!

Peace...

Tom

But AFAIK when Gimp edits an image, it removes the Exif Orientation

Whatever it is doing it is doing it 100% wrong 100% of the time and I
have to go into the file with VIM and remove the exif.

No such problem for me, and again, there are free tools to remove EXIF
if necessary, for instance with ExifTool:

    exiftool -all= {file}


Or it can just be done correctly in the primary image manipulation tool,
within the Gimp


And somehow it is putting my name in there.  Is that really necessary as
if I don't have enough things tracking me the universe.

I don't think it is coming from my Cannon Camera.

Either your camera or you have entered a default comment. Create an
image from scratch with Gimp and see if it contains your name...


If you want, I can demonstrate this.  Remove the EXIF and it orients
correctly.


I just fixed
http://www.mrbrklyn.com/brooklyn/images/2020_09_fishing/bike.jpg

by MANUALLY removeing the EXIF data from near top of the file.
It was correct in the GIMP and sideway in most of the rest of the
world..most importantly in Firefox et al

You are not demonstrating anything, we need the before and after images.


I am aware of that.  I can demostrate it easily enough

Before =>
http://www.mrbrklyn.com/brooklyn/images/2020_09_fishing/IMG_4577.JPG

After =>
http://www.mrbrklyn.com/brooklyn/images/2020_09_fishing/IMG_4577.2.JPG

the EXIF needs to be fixed..

Thanks for posting the sample images.  Please excuse me but I don't
understand what the problem is.  Is it the "After" image is _not_
supposed to appear 90-degrees rotated?  When I view the "After"
image in Firefox (and Opera), it appears rotated 90-degrees.

Thanks!



The original is 90° tilted as I tilted the camera to get a verticle
image


It opens in the gimp sideways, as it should since I took the pic that
way.

The "after pic" is rotated to the correct position.
... or it should be.

It is in the GIMP

It exif is pointing it to the incorrect orientation now. 
This is an example of tech trying to make things "simple"
and they are not simple.  They are broken.  

When you rotation the image the exif that is saved needs to be
fixed, or eliminated.




Last, the exported image is what you see on the canvas, an dis the size
of the canvas. Out-of-canvas parts are automatically cropped on export,
there is no need to flatten the image first.


That is good.  But there is even less need for the crop to be broken
because someone doesn't know how to use CTL Z.

Crop is not broken... for most purposes (especially exporting the
result) it works as before. And if you set the "Delete cropped pixels"
option, just save your tool options to have it become a default for you.


This is doesn't exist in this gimp version, GIMP 2.10.


Actually, I finaly found it, under, of all place, dockable dialogs :(


BTW - what it does, in addition to just being annoying, is it
takes screen space.  It is broken.  It was working perectly.
This is not trivial word play.  It was working.  It cropped
perfectly, and now it leaves the canvas too large, produces
a confusing layer, takes up unecessary screen space, and fails
to actually crop because someone didn't know how to use CTL Z

This defines broken
http://www.nylxs.com/images/gimp_broken.jpg

If you don't like the frame of your crop then just CTL Z and recrop

Its not that hard.  Even a graphic artist can do it.
