AVOID PEOPLE TO COPY IMAGES OF YOUR WEBSITE
Copying Images |
If you don’t want
other people to download images from your website, don’t put them online
because – the way the web works – it is almost impossible to prevent someone
from copying or saving your images.
However there’s
one little way that may discourage the less-technical people from casually
copying, or even hot-linking, to your web images.
To give you an example,try
saving the following image to your computer using the standard “save as”
option.
The “save
picture” option under right-click is still available for the above image but
instead of downloading the actual photograph, all it
would save is a blank
image. Also, the URL for the image (under Properties) would appear as some junk
characters (it’s called a data URI) and thus would deter the non-techies from
hotlinking to that image.
Here’s how you
may implement something similar for your own images:
The standards
embed code for an image looks something like this:
<img
src="photograph.jpg" width="500" height="250">
What you need to
do is change the value of the src attribute to point to a blank image and then
add a new style attribute to render the actual image. Also make sure that the
value of the height and the width parameters are exactly the same as the actual
image.
<img
style="background-image:url(photograph.jpg);" src="data:image/gif;base64,
R0lGODlhAQABAIAAAP///wAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw==" width="500"
height="250">
This is like
overlaying a completely transparent screen over your photograph and anyone
trying to save the image will end up downloading that screen instead of the
image.
Obviously, there
are simple workarounds to get around the above method. For instance, a copy of
the full image will still be available in your browser’s cache. You may look at
the HTML source or may even save the image using screen capture but again,
these techniques may not always be known to the
