Some of my forum members complain that their images look fine everywhere but once they upload to the forum then they rotate.
I tested this with one of their images and this happens with me. In my searches it appears that ImageMagick may be rotating these images based on exif info but I am not sure. I had switched years ago from GD since it uses more resources.
This is what I think is happening:
Certain images apparently has EXIF info in them that when uploaded to the forum they are auto-rotated 90 degrees counter-clockwise.
These appear to be images taken on an Iphone in landscape mode (at least what I have tested) where the image looks perfect on a computer. It can upload to social media sites without problem.
But when the member uploads, it goes from looking correctly to rotate 90 degrees counter-clockwise
Please note that THIS forum has this problem too! I have uploaded the original image and on the computer and everywhere else except vbulletin it is uploaded the way it looks on the computer. Once it is uploaded to a vbulletin forum, it rotates 90 degrees counter-clockwise. Please notice the attachment looks fine once you click on it and see the original but it is rotated in the wrong orientation before clicking. It is the same image that the forum rotated.
I asked this on vbulletin.org a few days ago and nobody has a clue how to address. On that site and mine it shows the rotated thumbnail and then if you click on it then you see the original that looks perfect.
Keep in mind that most uploads are fine. It is only certain images....
How can I disable whatever is auto-rotating my member's images?
No additional plugins related to images are used at all. The forum uses ImageMagick on 4.22 pl1
Is this a bug in vbulletin that needs to be fixed? An image uploaded should be presented as uploaded and not turn on it's side. (just like every other site)
Help! Thanks in advance for assistance.
