1) suggestion for you: try Zenphoto instead (www.zenphoto.org). ZP takes exif and iptc metadata from uploaded images and writes it into database EVEN IF YOUR SERVER HASN'T GOT EXIF EXTENSION! So the image's default datetime is its original creation date, that means date and time when picture was taken!

2) suggestion for the team: please take a look at the Zenphoto code. I believe you as programmers should understand how they made possible that their CMS reads exif/iptc from images ANYWAY. In case when you implement this in Piwigo, I may have many reasons to use rather Piwigo than ZP ;)

I was using Zenphoto, and switched to Piwigo, due to the following reasons:

- lack of documentation
- code is hard to work with, if you want to make changes.
- lack of help on the forum.
- attitude of the lead developer, and the way he treats people on the forum and in the bugtracker.


Piwigo has much better documentation, a great forum with lots of help, and great answers to your posts.

Better this, than a lot of features with no documentation on how to use them,  and in some cases features that do not even work, along with a lead developer with a horrible attitude. If you do not believe me, just take a look at some posts in their forum and bug tracker.

As a developer, I hope done the road that I will have some time to help out on this project. In the meantime, I am so happy I found this project, after wasting some much time with ZenPhoto.

Actually you can test this little library that they use.

Its most actual version is downloadable as zip here:
http://www.zenphoto.org/trac/browser/trunk/zp-core/exif

And here is the link to the original creator of this library. His zip file contains also index.php and sample picture that you can use with the latest version of this library.

Hi plg,


The JpegMetadata don't use PHP extension/functions to read exif, xmp and IPTC metadata. It read an interperter it directly in the binary image file.
As a consequence, it's slower than using a compiled library (dedicated to PHP or external)

About this library, she's now a little bit out of date: it works very well for common metadata (specification don't change each year), bur for dedicated maker and/or camera metadata I think I have to update the plugin.

Hi, any progress?
When we need sort data it is still necessary that the data is in db table. And the "uploaded" date and time has a secondary importance after the date/time taken.
The library I mentioned is freely available, so... :)

I forgot to mention that the library used by ZP reads and writes the metadata from pictures automatically into database at the moment, when the new pics are uploaded (incl through ftp) and the site visited for first time after that.
