Thanks again for your generosity!

Thank you so much for this!

I did get confirmation (sort of) from one of the WordPress for iPhone forum moderators that the iPhone client does strip EXIF GPS data from images when they are uploaded. He didn’t say whether this was something they did or something that was forced upon them by Apple not exposing this functionality, but since EVERY other iPhone app I’ve used also seems to strip off the GPS EXIF data, I suspect you are right that it has something to do with the Apple libraries used.

Also, I’m sure you’re aware that version 2.3.1 of the WordPress for iPhone client was just released and, while it still doesn’t maintain the photos’ GPS EXIF data, it DOES add geotag data to the post meta, which I think I can work with.

For Twitter applications, I can do something similar. Tweetie and other apps also strip off the uploaded photo GPS EXIF data, but since Twitter stores the geotag data, I can go fetch the geotag data from twitter, add it in to the post meta data and use that info.

So, I’m thinking of modifying your awesome Thesography plugin to work with post meta data in addition to EXIF data. It’s a bit convoluted, but I think it will work.

Regarding iPhone imaging and EXIF, sadly Apple hasn’t made EXIF available in their API so any application dealing with images will probably strip the EXIF data. This is what I was told by a developer when I expressed my disappointment that EXIF data wasn’t saved by his app; I think it was the geo data that I specifically wanted. So yeah, that sucks! You either need to download it straight from your phone to your computer without editing or add the geo back in at some point. :-(
The other thing the WordPress app didn’t do last time I checked was attach photos to posts properly. It inserts them in the post but doesn’t attach them in the metadata.

Thanks so much for responding. After running some more tests last night, I’ve solved my problem…sort of.

I have seen your filter and your great plugin. In fact, it was your Thesography plugin that inspired my current project. I’m trying to display geo data for images that are posted via Tweetie or the WordPress for iPhone client.

What I’ve figured out is that while the images that the iPhone takes do have GPS EXIF data included in them, it appears that both Tweetie and the WordPress for iPhone clients strip the GPS data (and most of the other EXIF data) from the images before they are uploaded.

So, I’m back to square one :-) I’m going to see if I can come up with a way to provide the GPS data through some other channel. (If anyone else who reads this has any ideas, I’m open to them.)

Thanks again for responding and for all of the greatness here on your blog. This is one of my consistent favorite spots on the internet :-)

I’m not really sure what you’re doing with the code you showed, or how it works, so I can’t help you with that specifically, but I know my filter works.

I also wrote a plugin called Thesography that includes the geo filter and provides a shortcode or function to display the EXIF in posts.
