Hi

I am needing to extract metadata from image files primarily canon _.CR2  
and  
photoshop_.psd files so I can use the metadata in a mysql database.

Does anyone know of any available routines to help with the task… I  
would  
rather not have to reinvent the wheel (beside I am lazy ).

I’m not sure about the canons, but on my nikon I can grab the meta  
data from the jpeg thumbnail from my nef images (nikon’s raw file).  
It doesn’t give me everything mind you, but it does have a fair amount  
of data. I can’t recall the name of the program I was using to grab  
the info with, jpeginfo might actually be it…
