This article continues the series on watermarking your digital multimedia content. If you are using or planning to use Picasa to organize, view, edit and share digital photos, read this article for information on how to use this software for copyright protection of your digital images in batch mode.
Get Started Batch Watermarking
Run Picasa 3.9.0. Select the photos you would like to watermark and click Export as shown in the screenshot below:
This invokes the ‘Export to Folder’ dialog:
Follow the steps listed below to protect your copyright in a batch:
- Specify the Location folder to which watermarked images will be exported (copied).
- Specify Image Size if required. Leave this option unchanged to use the original size.
- Select an appropriate image quality. Let’s use Maximum.
- Select the Add watermark option and type the text.
- And you are done. Click Export to run the batch watermarking.
- In Picasa, image watermarks are not supported. Only text can be used.
- You cannot specify font settings (font name, size, color, etc). In Picasa, a watermark is white text (for dark photos) and black text (for light photos).
- You are not allowed to specify the location at which a watermark should be embedded. In Picasa, a watermark is added to the lower-right corner of photos.
Finally, let’s measure how much time it takes Picasa 3.9.0 to embed a custom string in multiple images. The results are shown in the table below:
