Hi,
I have a DSC 933L camera that uploads jpeg-files every 30minutes via ftp onto my website.
How can I add timestamp (time+date) onto the photos?

Thanks

Hate to ask - but have you read the manual for the camera?

Kjartan_Haugen

Yes, and the d-link webcam I have does not offer timestamp directly on photos.

The manual does mention:

This will be the name that precedes the time, for example DCS9302010072116425101.jpg. This means that the camera took a
snapshot in the year 2010, July 21 at 16th hour (4 o’clock), 42 minutes and 51 seconds and it is picture number one.

Maybe you can extract this information..

Yes, I think that would be possible in some way.. but im not sure how to "timestamp" a photo with that data.

Does it need time stamping or would a time reference on the picture be sufficient?

If you need to do something with the image then the PHP image libray of functions provided by the GD library might be a good starting point.

This may help you :

DCS9302010072116425101.jpg can be split

If the file name length is constant, then you could use the following.

$full_filename = "DCS9302010072116425101.jpg";

$stamp_str = substr ($full_filename , 6, 22 );

$year = substr ($stamp_str , 0, 4 );
$month = substr ($stamp_str , 4, 2 );
$day = substr ($stamp_str , 6, 2 );

$hour = substr ($stamp_str , 8, 2 );
$minutes = substr ($stamp_str , 10, 2 );
$seconds = substr ($stamp_str , 12, 2 );

$picture = substr ($stamp_str , 14, 2 );

Will extract to variables that you can then format like so...

$timestamp = sprintf("%s/%s/%s - %s:%s:%s - [%s]", $day,$month,$year,$hour,$minutes,$seconds,$picture);
