I don't know if I am being overly paranoid, but I have started removing the EXIF (Exchangeable Image File Format) data from JPEGs before posting them online.

Here is some info on EXIF: Exchangeable image file format - Wikipedia, the free encyclopedia

In theory, LEO could use the data to cause us harm.

Here is a program called J-Strip that removes this data. If nothing else, it saves space by making your JPEG file slightly smaller:
Download jStrip 3.3 Build 00305 - Reduce the file size of JPEG images without sacrificing image quality - Softpedia

And, it is freeware.
Be safe and good grows to all!!!!!

Well, I've played around a little with J-Strip and it works very nicely. It gives a log that shows what has been done to the JPEGS. Here is a sample-----------------------------------------------------------------

Thanks for the heads up. I knew there was embedded content in JPEG images but I didn't realize it contained global positioning coordinates for devices with GPS or triangulations from cell phone towers. You've confirmed my suspicions. Hmm, I wonder what they plan on doing with this geocoding information, something tells me it's more than flickr.

This would also be good information to share with other sites for security. If we know this stuff, it is our job to share it. I will add this post to the politicall forum so others can read it. If we know how to disable it then others can as well.

Thanks folks.

Peace

Hey Michael.

I used the EXIF settings built in to the PhotoPlog Pro program. In fact, all EXIF data should be off now.
