[FIXED] How do I watermark an image?

Issue

I have a jpg file that i want to merge another image png file on it. I am not sure how to implement this using php?

Solution

you can use gd's imagecopy function.

This function is used to copy a portion of image from source to the destination

imagecopy ( 
           $dst_im ,   // destination image (resource), imagecreatefrom(gif|jpg|png)
           $src_im ,   // destination image (resource), imagecreatefrom(gif|jpg|png) 
           $dst_x ,    // x cordinate in destination where u want the new obj placed
           $dst_y ,    // y cordinate in destination where u want the new obj placed
           $src_x ,    // x cordinate in source from wher u want the new obj placed
           $src_y ,    // y cordinate in source from where u want the new obj placed
           $src_w ,    // the width of the object to copy
           $src_h      // the height of the object to copy
);

As pointed in the comment in the above code, you will have to create an image resource for both destination and source.

Typically done using

 $src = imagecreatefromjpg('image.jpg');
 $dst = imagecreatefromjpg('watermark');

The remaining portions are just simple co-ordinates.

Also don't forget to visit imagecopy yourself.
