Those who haven’t seen  the online photoshop tool created by me, just click here: http://www.sajithmr.com/photoshop

Today we will implement the watermarking on images using php gd library. Intelligent watermarking means, apply a logo or a watermark image on another image by measuring the color depth of the applied image. For this water marking, use png images as logo or watermark  for better results.

Live example for watermark implementation: http://sajithmr.com/photoshop-tuts/watermark/addwatermark.php

You can see different watermark location by changing the x1,y1 and x2,y2 parameters of the following url:

Today we will implement the browse photos area of online photoshop

Those who haven’t seen the online photo editing tool, click on the above icon (baloon)

You can see the browse area implementation here: http://www.sajithmr.com/photoshop-tuts/browse.php

What you need for this is 4 php functions: is_dir , opendir, readdir, filetype

Normal file browsing can be implemented using while loop with above four functions.

See its usage:

if (is_dir($dir)){if ($dh = opendir($dir)){

while ( ($file = readdir($dh)) !== false   )

{

if($file != '.' &&  $file != '..')

{

//if it is a directory show folder icon

if(  filetype($dir .$dir_sep. $file) == "dir"   )

{

//display a folder icon here with folder name using img tag

}

else

{

// display image here in img tag

}

}

}

}

}
