That's fine by me... I just was looking for a way to store an arbitrary 
amount of data for each image in as efficient a storage manner as 
possible.  Does anyone have any objections to just storing it as a 
single attribute (image_exif_data) as a delimited string?

I was thinking something along the lines of:   
name=value__name=value__name=value

the "__" (two underscores) is very unlikely to ever bee seen in either 
the names or values of the exif data.

If I went the route of using fixed attributre names, I'd have to 
hard-code all the possible EXIF fields into the code, making a little 
more work to maintain.  If there is no database storage benefit to using 
delimited values (and there are drawbacks), just say so and I'll go down 
the multi-attribute route.
