Retrieving EXIF Data

[Motabobo]

How do i retrieve EXIF data from picture without using a registered dll ? (can't register dll on free web server).

I would like some info like the date the picture was taken, the camera model, if the picture fired the flash or not, etc...(called EXIF info). I really don't want a database to store that info, or a text file or xml. Why care about using another file while all the info are already in the picture file ???

The only script that worked for me is ImgX from Atalasoft and it still uses a registered dll :

Please help !!!

Hi thanks for the info !

Unfortunately, i have not been able to retrieve any of the exif data. Using the binary technique, i've only managed to get filename, filesize, image dimension, color depths and the type of image.

The information i would like is more like the file comment, author, copyright and some specific image data like the shutter speed value, Aperture value, subject distance, etc... (all of which i can only have by ImgX so far...)

Any other idea ? or maybe i just missed something on microsoft's site ?

Thanks !

I think it would be in the file attributes since you can get the info (under WindowsXP) by right-clicking the image and selecting the summary (advanced mode) tab.

But i am a bit confused :
EXIF data is additional information 'meta-data' that is included along with the image in the files created by a digital camera. Exchangeable image file format (EXIF) is the international file format standard for digital cameras.

There must be a way to retrieve that info without registering and activex or dll ?!?!

I really don't know where it is stored :(

I've browsed the link you provided to me on msdn but there is nothing that refers to exif data !

Maybe that link could help (this is like chinese to me !) :

Oh ! :rolleyes:

Anyway, do you have any idea of how it may be done ?
The link i posted talks about the data structure but i don't know if it will be of any help :confused:
