Problem: Internet Explorer cannot read the EXIF data from images. So, if you take a picture upside down within the collector app and you will open this attachment later on your desktop, Internet Explorer will show this also up-side-down.
Esri solution: Take your picture not with the standard camera app from your i-pad, but use instead for instance ‘Camera +’.
My proposal is to make it possible to set a default camera application within the collector app.
