Thanks! I was looking for a way to convert a captured image to sepia using the GD library, and you had the perfect answer for me.

Hi,

Nice codes here, but i want to block the adult images from my site http://www.neatstat.com and only want to display the good, clean images. How do I block these adult images?

Do you have any image filter to do that like bad words filter?

Any help will be much appreciated.

Thanks
Pummy

Do you know how to create “Virtual Product Samples” with any PHP script? are you aware of any such script which helps in creating 3D samples of various images and finally combined as one virtual sample.

I’ve used GD in the beginning, but as you go along with larger images, or other file formats, it’s better to leave GD alone and use ImageMagick. GD can also be a memory pig and the use for it is limited.
With IMagick (in response to EmEhRKay) you can use masks to cut out your images (to make rounded corners). You can rotate, flip, flop, convert, resize, etc. within the blink of an eye. You can even create thumbnails of 500MB Illustrator documents if you want (not that that’s recommended) :-)

I’ve been wondering, but not enough to investigate, how to make images with rounded corners, like facebook — any idea how?

Hey David,

Great stuff, I’m a huge fan of using the GD library to help achieve certain effects with images. I hope you don’t think I’m link whoring, but I wrote a 2 part article for ThemeForest on exactly this topic and thought you might find it interesting:

Keep up the great work!

Case for IMagick/et al:
– same function to opens all image formats
– memory management (helpful for very large images)

//to black and white, then sepia
if(!file_exists(‘dw-sepia.png’)) {
$img = Imagick(‘dw-manipulate-me.png’);
$img->setImageColorspace(GRAYColorspace);
$img->sepiaToneImage(80);
$img->writeImage(‘db-sepia.png’);
$img->destroy();
}
