If you capture images as JPEGs, and then make changes to JPEG files in the Develop Module (or in Quick Develop) in Lightroom or in Camera Raw in Photoshop ,and post those original JPEG files online, the adjustment changes will not be displayed. You must have Lightroom or Photoshop render a new version of the JPEG with your changes applied (via Export, the output modules and/or publish services).
Why? Well, when you make changes to your files in Lightroom (or Camera Raw), you can choose to push settings such as copyright and keywords into JPEG files. In Lightroom you do this by choosing Metadata > Save Metadata to File or by checking “Automatically write changes to XMP” in Catalog Settings > Metadata. In Photoshop, you add your information in File Info or in the appropriate panels in Bridge. Most other programs, (if they’re savvy enough to read IPTC data) can read information such as copyright and keyword and display this information.
But other programs (including browsers) are not able to read changes made in Quick Develop or in the Develop Module in Lightroom or in Camera Raw in Photoshop and render it, so you need to export your modified files (in order to render a new file with the changes applied) and post those files instead of the original JPEGs.
