<p>REALLY appreciate the great help ali/everyone,</p>
<p>I ordered the $2 AddWatermark app from the Google Play Store, looks very promising and has a MUCH better interface than the iWatermark app.</p>
<p>There was a workaround method to use the Stickit! app for adding a logo to pictures, but this seems more direct and useful (especially with the ability to adjust opacity). </p>
<p><strong>PS</strong>: Is there a best-practice or method and file-extention (png, gif and so forth) to convert solid color unified background to a transparent type, for use as a logo and superimposing on images? THANKS!</p>
