With most HTML-based albums, it is VERY easy to drag an image right off the page for anyone interested; so-called "right-click blocks" are easy to circumvent. All browsers can be made to display the source code of a page, and therein is the URL of the original image, for anyone to see. Some tricks with frames &c can make it a little more difficult, but that´s only seen as a challenge.... A Flash-based album is (can easily be made) immune to these simple ways of pilfering, but more accomplished hackers will overcome that obstacle, too. And, for simpler souls, there´s always the possibility of a screen dump (where the perpetrator does lose some image quality in the process). Invisible watermarking can be used as evidence when (if) a thief is caught, but doesn´t in any way prevent "personal use", including making prints. So, any image worth money must either be shown too small to be useful, or have some visible (and thus distracting) watermark within the image area itself. Neither is ideal. Per |
