It has been found that some of the most popular social media sites will delete a photograph's metadata.

Research undertaken by the International Press Telecommunications Council showed that sites such as Facebook, Twitter and Flickr will remove photographer's metadata from images that they host.

The IPTC tested a total of 15 social media websites, with an aim to find out how image sharing through upload and download effects the embedded metadata of an image.

Flickr and Facebook were found to remove most of the metadata from images uploaded, while Google + came out on top, retaining all types of metadata in its images.

To see all the sites tested and how they did, take a look at the IPTC website.

The report is uncertain what happens when you have a pro Flickr account.

I just checked mine by right clicking one of my pictures and selecting "Save Image As..." and the resultant image appears to have none of the original exif data that was included when I uploaded the picture.

Well I downloaded/copied some of mine from my Flickr Pro and it got saved as a smaller jpg @ 240x240 pixels @ 72ppi (Though it says dpi, wish everyone would read up on dpi & ppi and get it correct). Was loaded into Flickr as a 1050 pix and others at 1400pix @300ppi.
So how on earth can someone use the Stolen image at those sizes I re-downloaded. Don't make sense to me.

I just did a further check, if I download the original size picture then the EXIF is intact. Downloading any other size results in an image with no EXIF.

MrDennis: the size that gets downloaded would depend on what sizes are available via your Flickr account - but I expect that it would be possible to get to bigger sizes.
