CTRLA Hidden Image Creator, as the name suggests, is a free program that lets you insert watermarks into your images. This way you can identify them quickly by your signature or stamp.
Once you`ve assigned the watermark to your image you can view it correctly via your Internet Explorer web browser, and to select it you just press CTRL+A, and it is selected to cut and paste into any document or webpage.
This CTRLA Hidden Image Creator utility includes a collection of tools you can easily use to personalize the resulting image, modifying the quality of the mark, the type of file you are working on, or the invisibility level of the second image.
