The information you have on the Flickr photo site is not correct. Flickr fully supports EXIF data. Flickr does not modify or delete any EXIF data associated with the uploaded JPEG image. You must make sure that if you export an image from Photoshop or Lightroom that you do not remove the EXIF data. To the right of each photo on Flickr is a link named "More Properties" that when clicked on will display all of the EXIF data for that photo. In addition, Flickr allows users to display or download 6 image sizes. If you click on the menu item "All Sizes" above the photo, the following will be displayed. This example is for a 10MP original.
