Pictures showing up rotated and how to solve this

Postby Oishii » Tue Sep 13, 2016 6:24 am

Imagine ... you are writing a nice post and about to add stunning images to it. But some of the pictures show up in a rotated form. And whatever you try to get the correct look, they keep displaying in an incorrect orientation.
Very annoying !

The image keeps showing up like this :shock:

Instead of this :

Recently, our members Steve and Alex mentioned this, so here is a little tutorial on why this happens and how you can solve this.

For members interested to know the reasons for photos displaying in an incorrect orientation, we share a little background.
But if you are instead looking for a practical solution, without bothering with the background, just jump to the next section. ;)

Why your pictures do not always show up correctly rotated ?

There are basically two different ways a photo can be rotated.Traditionally, computers have always rotated images by moving the actual pixels in the image.
But, digital cameras didn’t bother rotating images automatically. So, even if you used a camera and held it vertically to take a photo in portrait mode, that photo would be saved sideways, in landscape mode.
You could then use an image editor program to rotate the image to appear in its correct portrait orientation. The image editor would move the pixels to rotate the image, modifying the actual image data.

This just worked, everywhere. The rotated image would appear the same in every program…as long as you took the time to manually rotate them all.

Manufacturers wanted to solve this annoyance, so they added rotation sensors to modern digital cameras and smartphones.
What they did basically was to add a little piece of information to the picture, which would automatically react to how the picture should be rotated.

The problem our members experience is that this little piece of information is not always read the same way on different computers.
It would lead us too far to show you how to change this bit of data in the (exif) file.
Luckily for our members there are a few easy solutions.

Fixing the orientation of your photos

First, try to correct the orientation with your image editor program.
It is best to first delete the image from your post on the forum. Correct the orientation with the appropriate program on your computer and when this has succeeded, just re-upload it and add to your post.

In case this does not work and the photo keeps displaying in rotated form, you can solve it by taking a screen shot.
But if you feel uncomfortable with this, do not hesitate to just ask one of the Mods to orientate your image correctly.

Taking a screen shot.

The screen shot will not have the added little data that bothers with your image orientation.
So it will be no problem to rotate it to the correct form.

* for PC users

First you want to capture the image – Assuming the area you want to capture is displayed on your screen, press the Print Screen (often shortened to “Prt Sc”) key, typically located in the upper right corner of your keyboard, to capture a screenshot of your entire display.
Alternatively, press Alt + Print Screen to merely capture a screenshot of the active window.

The screen shot will be on your clipboard. Just open your Paint program to make the necessary adjustments.

* for Mac users

Set up your image just exactly the way you want to see it to be as a screen shot.
Press Command + Shift + 4 all at the same time.

- Place the new crosshair cursor at one corner of the area you want to capture (for example, top left), and click and hold.
- Drag the crosshairs to the opposite corner (for example, bottom right).
The crosshairs give you a precise pixel count if you want a specific size (or even to measure).
- Hold down Option to change the lock point to the center of the area. Hold down Shift to lock all sides but the one in the direction you're currently moving.
When you're happy with the area, *lLet go** of the mouse button or trackpad. Whatever is contained in the outline is what you'll screenshot.
You'll hear a camera click sound, and your screenshot will appear on your desktop in .PNG format, with the title Screen Shot [Date + Time].
- Double click on the screenshot to open and share it with Preview. Right click and choose Open With, or drag and drop it, to open and share it with another app.

Fixing photo-rotate more simply

Postby chonchon » Fri Oct 07, 2016 10:54 am

Oishi's comprehensive thread is locked so please allow me to post here how I got around auto spin when posting iPhone photos here.

In order to 'fix' the orientation of the photo I go to Edit, then I 1/4 rotate 45 degrees x4 in order to bring the photo right back round to its original orientation. When the Done button highlights, I push that. This seems to save it more securely.

Since discovering this I have had no more problems.

MOD EDIT - Thank you for adding this advice, Piers ! ;) We have merged your post with the existing one and unlocked the topic so other members can share their experiences and advice - END MOD EDIT
