Default Help...attachments odd problem w rotation

I'm not sure if this is the right forum to ask for help with my problem.

I take my orchid pics with my iPhone, lets say portrait or vertical format.

Then email them to my desk top mac where I download them. They look fine.

Then I write my post and attach the pic...
When I preview my post the pic is always rotated 90' to the left and is now sideways or landscape view.

So I delete it form the post's preview, open the pic on my mac in "Preview" app where it looks fine. Then using the rotate tool I rotate it four times bringing it back to the vertical where it started. I save the changes to the pic file. (changes ? its still the same vertical pic!)

Then I upload it on the orchid board, attach it to the preview and the re preview it and its fine so then I just post.

Anyone have any idea why I have to rotate the pic 360' back to the way it was and then it posts properly?

I am finding this more mysterious than the orchids life cycle!!

It seems this is a peculiarity of this site. I've dealt with it too.
There are several posts somewhere dealing with this, but I'll offer the one I use from my phone. There is an app called Postimage. Upload your photo to the app, scroll down and choose the copy button that says "hotlink for forums", then come here and paste that link. Your photo will appear in your message.

It's a bug that appeared in one of the last forum updates (many years ago) and there's nothing we can do about it and you aren't doing anything wrong. Over the years I've gotten used to having to turn my head to look at vertical photos!

One apparent 'fix' is to open the photo on your computer in editing software, rotate it out and back into vertical position and save. It rewrite something in the photo code which the forum them understands as 'post this vertically'. I haven't tried it yet since I usually post bbcode from my photo website.

The rotated images (if any) seen on orchidboard is probably not a bug as such. But is instead the orchidboard forum software isn't doing some processing on the photo to make some amendments to the orientation information of that photo.

In cell-phone pics ...... the actual 'UP' direction is generally the right-hand-side LONG edge of the phone. It means - having the right-hand-side long edge pointing straight upward to the sky is considered to be 'normal'.

Holding the phone vertically while taking a shot is sort of like tilting the 'up' direction 90 degrees clockwise. The cell-phone has orientation sensors. And the orientation information is stored with the pic. So 'vertical' pics taken with the phone will come out appearing horizontal - because the actual 'up' direction is not the vertical direction for many cell-phones.

So image viewing software can tap into that orientation information (embedded in the photo data) and allow the viewing software to re-orientate the image so that it becomes displayed in the way we want it. Or ----- some image editing software can look at the orientation information, and then alter that orientation information (permanently) ----- such as making the 'vertical' direction become the 'new' UP direction.

The processing software that I mention at this link here (link) changes the 'up' direction permanently - but the software runs in MS Windows systems for now.

Also - the reason why the pics 'look' like they're in the 'correct' orientation when viewed in the cell-phone photo-gallery ----- is because the cell-phone software looks at the orientation information, and it just graphically displays the image in the 'correct' orientation - without actually modifying the orientation information stored within the photo's file.

Wow..your so knowledgable !!!
Are you a software developer yourself?
For me, I just found that on the mac, I'd open the pic in Preview, rotate it 4 times back to vertical as it was , save changes and then it posts vertically....not sure what that changes i the metadata but must be something?
Just for fun, any ideas as to what might change in the file or its metadata?
Now you have me curious !!!
Thanks

I suspect the issue is that newer phone camera software isn't recording the orientation data the way it used to. When I posted photos from an old phone to this version of OB the orientation was always correct. Using a newer phone it is not correct. I don't know whether EXIF standards changed or phone software designers got lazy.

DD ----- I'm not a software developer. Part of our schooling involved some computing, so that helped me to just be able to some intermediate type programming. These days - I think the schools make everybody need to do some programming.

With the orientation information in these phone-pics ...... I forgot to mention that the stored orientation information is based on what the orientation sensor was providing at the time of the shot.

So if the photographer with the cell-phone takes a 'vertical' position shot (with samsung/apple etc logo facing upward), then the stored orientation information will be a code equivalent to 90 degrees clockwise. Why 90 degrees clockwise? It's because holding the phone with the right-hand long side of the phone pointing upward is the actual 'UP' direction. So holding the phone in the 'general vertical' direction (eg. with the samsung or apple etc. logo facing upward) will make the sensor record a 90 degrees clockwise tilt.

That sort of information is stored within the pic file itself. The information basically tells us which orientation the phone was actually held when the pic was taken. So knowing that information allows software to :

1) 'automatically' display the photo with the 'correct' orientation that us humans want to see. This is done without altering the photo file at all.

OR

2) automatically check the orientation information, and then alter the orientation information in the photo itself - alter it permanently ------ so that the new orientation information will be changed - so that every image viewer will just display the image in the 'correct' orientation.

OR

3) Using a photo editor software like photoshop etc to manually rotate the image ----- rotate it so that it looks 'normal' to us. When the photo-edited image is saved ----- the 'UP' direction will be exactly as we see it with our eyes.

It's not a bug, it's a feature.
