Sideways images be gone!!!

[WingAdmin]

This one has been driving me crazy for months. I've finally cracked it - it was a bizarre error that came over from when we switched servers last.

In any case, images should no longer upload onto the site and show sideways (or worse) when they were taken that way.

Avatars work differently, and I'll still have to work on that one a bit more.

1:16 am, time to call it a night!

it is aggravating when images come up that way....
I have GIMP set to "auto rotate" so when I get thru with an image, it is always right side up.

The problem is modern digital cameras and smartphones have orientation sensors, so they know which way the camera was turned when the picture was taken. But instead of actually rotating the image when it is written to the memory, it writes out a regular "landscape" image - and then inserts data into the header of the image (called EXIF data, if you care) saying "rotate the image THIS way when it is displayed."

When the images are being processed during uploading to the site, this EXIF data is deleted, for privacy reasons - a lot of cameras (and especially smartphones) embed all kinds of stuff in the EXIF header that you don't necessarily want public. For instance, the exact lat/lon of where the picture was taken, that sort of thing. In doing so, the "rotate image THIS way" data was also being lost.

I had to rewrite the code to extract this rotation information and save it, then use it when processing the image so that the image would end up rotated correctly.

Hi again, WingAdmin. Could you share anything about your code rewrite to extract and reuse the rotation code? My buddy that owns an HD forum might be able to incorporate something similar if you're willing to share. If not, I would understand. You can PM me if appropriate.

TIA. Ron

You'd be my hero IF you could do same for idiots taking videos to send to the network news so the rest of the world can watch vertically shot images on a WIDESCREEN tv with 2 blurry images and the vertical in the center 1/3.
