When the watermark appears, this means the imagerotator.swf was installed from the link NextGEN provides. The file that was included in your .zip download purchase includes a license free copy of the imagerotator.swf file. To remove the watermark you’ll need to delete the file you installed (most likely located in wp-content/uploads/…) and insert our file in the wp-content/plugins directory on your server via FTP.

You may find our file located in your Photocrati Theme Folder: photocrati-theme >> plugins >> imagerotator.swf (if you chose to ‘move NextGEN’ under Quick Set-up, you may be able to skip this FTP step)

Then, remove the URL in Gallery >> Options >> Slideshow settings, and click ‘search now’. Having removed the file you previously installed, and uploading our copy of the file, NextGEN should successfully find our copy and your slideshows will now play without the watermark.
