ImageMagick PHP writeimage() does not create new image file

I am writing a code to distort an existing image, then save the new image in a separate file. Images are .jpg
The image is distorted and
echo $image;
displays the distorted image to the browser, but
$image->writeImage("newimage.jpg");
does not save the new image in a seperate file. No error messages.
Why?

How can I get exact urls of product images in opencart?

I got products from product and product_description tables. I also found image column in product table. But I can't get resized images? How can I?
Thanks in Advance..
Resized images are stored in image/cache/ folder.
Resized images are created only when resize method is called. Like in catalog/controller/product/product.php you can see following code which will resize the main image.
$this->load->model('tool/image');
if ($product_info['image']) {
$data['popup'] = $this->model_tool_image->resize($product_info['image'], $this->config->get('config_image_popup_width'), $this->config->get('config_image_popup_height'));
} else {
$data['popup'] = '';
}
Here the resize method takes database product's table image field and height and width given in setting of admin.
This will create resized image at image/cache/"IF ANY FOLDER"/ and the name of the image will be like "NAME_OF_THE_IMAGE"-width*height."EXTENSION_OF_IMAGE"
For eg:
If you product table's image column holds catalog/demo/imac.jpg then you resize it with width=100 and height=100 then it will be cache/catalog/demo/imac-100*100.jpg
Take into consideration that resized images are created only when you load the controller, once it is created it will be there.
So taking your problem into consideration, you have to recreate your image urls as described above and create resized images(only if you need images also).

Display colored images in greyscale on web page

How can I convert images on my website into greyscale? I don't care if it's PHP or JS, but I think PHP is nicer.
In particular I have a blog with various posts containing images, and I want the thumbnail images that preview the blog post on the index page to be greyscale while the represented images in the blog post stay colored. These thumbnail images share a class called .post-thumbnail there the img tag is inside the element with that class.
All I want is something that would look like this in CSS is there would be that property:
.post-thumbnail img { image-transform: greyscale; }
In PHP or JS.
Quick search on StackOverflow finds this:
$im = imagecreatefrompng('dave.png');
imagefilter($im, IMG_FILTER_GRAYSCALE);
imagepng($im, 'dave.png');
