How to watermark all your uploaded images
How many of you wanted to place a watermark on all of your images?
Let's say you are just starting your own blog and the first solution that comes to mind is to fire up Adobe Photoshop or any other image editing program and place a watermark on all your images. It is time consuming but it will work.
But what if you have a blog for a really long time and you just decided you want to watermark all your images? You would have to copy all your images from your blog to your computer, open all of them up and add a watermark. Not good.
But what about the original images? What if you ever need them without the watermark?
Here is my solution. I have been using this on a number of blogs and it does the job really well.
What we are going to do is fake the display of an image. What we are displaying instead of the image is a php file that processes the image and ads a watermark to it. The url of the image stays the same, the watermark gets printed on the image and best of all the image on the server doesn't stays intact.
All you need is a bit of code in your .htaccess file, a php watermark processing file and a watermark image (png preferably).
