osx - Why some picture was rotated is iOS device? -

-

it's strange same picture display different on pc/mac/ios device.

this url of picture: http://imgtest.meiliworks.com/pic/d/b3/0d/1a6157b2828bbcbfadb0d4d114b0_600_2400.jpg

it's 77x310 in safari on mac osx 10.7, it's 310x77 in safari on ipad!

if download picture , open directly, it's become 310x77.

what's wrong picture?

your image contains exif orientation tag value of 6 (rotated 90 degrees left). not image viewers handle tag properly. don't respect it, they'll display image rotated 90 degrees right.
