I have attempted a fix of the "sideways iPhone image upload problem".
This may or may not work.
iPhones mark pictures as a landscape (sideways), even if they're portraits (upright), but place an "orientation" EXIF tag into each image to correct it upon display.
ImageMagick (the processing library for images on this forum) ignores that tag.
Therefore, this forum displays iPhone images sideways if they're taken as a portrait, unless they are manually re-saved on a computer.
I have made a modification which I think will fix this.
Please upload iPhone images to this thread -- one portrait and one landscape -- and see if this works.
TY
