division by zero error in exif.php in 1.1.6

firsttimeuser

i guess this may be due to some faulty exif data in the image (exposure time?),

the line err'ing was 370, so on line 370, in version 1.1.6, so i just muted the error:

from
if (($bottom % $top) == 0) {

to
if (@($bottom % $top) == 0) {

is this sensible?

line 371 was err'ing as well, so i added a check for zero to the code:

} else if ($tag == '829a') { // Exposure Time
if ($top == 0){
$data = 'Unknown';
}
else if (($bottom % $top) == 0) {...

anyway, there's a lot of if / elseif's there for the tags, wouldn't a switch be neater?
