Each of my JPEG files is over 1 Meg, and Read_exif_data seems to read the
Whole file and it ' s very slow. So I wrote a function to read only the
Beginning of each file:
function Read_exif_data_quick ($path) {
$tmpfile = "/tmp/read_exif_data_quick.tmp_file";
$in = fopen ($path, "R");
$out = fopen ($tmpfile, "w");
Fwrite ($out, Fread ($in, 15000));
Fclose ($in);
Fclose ($out);
Return Read_exif_data ($tmpfile);
}
And so far it works for all of my jpegs (taken with my digital camera).

I started drooling when I saw that PHP could read the EXIF information
Automatically for me. Then I found out this read_exif_data is not
Compiled into the standard Win32 build (think about including it please!).
To get around this I found the following program that runs from the
Command line and works really well.
It ' s actually a set of utilities that would even allow you to put EXIF data
into images.
It ' s freeware, but the license says no commercial use without written
Permission.

Perl Image::info module is capable of reading EXIF tags (places them into
An associative array). Can write a simple script to use the module and
It'll extract all or only required tags out of a jpeg file.
