Exif data aanpassen
Ik heb een probleempje.
Als ik bestanden upload naar mijn webhost dan kantelt hij alle afbeeldingen.
Wanneer ik de Exif data uitlees dan krijg ik als Orientatiepunt 8, Hoe hij dan staat kan ik hier zien. Weet iemand hoe ik die exif data aan kan passen naar 1?

}

maar dan wordt mijn image naam helemaal niet meer goed krijg ik dit als ik ene bepaalde foto upload
na de bovenstaande scrtipt is $fileTmpLoc=> Resource id #8 of #6 naargelang de exif informatie
hoe krijg je dit in het script verwerkt?
