Yup... that was the problem... the URL was indeed bad... Thanks for
the tip!
While I'm on the subject... I'm using CGImage because I read it would
actually parse more EXIF tags than using NSBitmatImageRep's
valueForProperty:@"NSImageEXIFData"
Just tested it... my initial image has like 50+ EXIF tags (camera
specific tags etc etc...)
My resulting images (one using NSBitmapImageRep, the other using
CGImage) both have 22 tags... so basically there is no advantage in
using one over the other??
And isn't there a more efficient way of reading EXIF data? Not even
half of the tags are read ....

Wait you might be onto something...
I was using [NSURL URLWithString]
instead of [NSURL fileURLWithPath]

one possible .. |kCFURLImproperArgumentsError is defined as -15. Is
the imgUrl ok? Can you send a Null dictionary to that function or
should you send an empty one? |

Well, apparently it's not a framework problem since I can use:
CGImageSourceRef source =
CGImageSourceCreateWithData((CFDataRef)tempData, NULL);
without a problem...
Any other reasons why CGImageSourceCreateWithURL would yield an
error code -15???

What framework has to be linked/imported to use CGImages? I
tried <Quartz/Quartz.h> but when I try to load an image using:
CGImageSourceRef source =
CGImageSourceCreateWithURL( (CFURLRef)imgUrl, NULL);
I get the following error:
<Error>: CGImageSourceCreateWithURL failed with error code -15.
I am already importing <QuartzCore/QuartzCore.h> because I'm
using CIImag, however, now I need to use CGImage and for some
reason I can't get it to work...
