从外部链接上传wordpress中的图像

I have image coming from external link

http://deomain.com/images.php?id=<id>

Now I want to upload image using above url into wordpress.

Please suggest code.

Thanks in advance.

In order to get started go ahead and download Grab and Save plugin. Once you have it downloaded and activated you will notice that whenever you went to add an image to a post “Grab & Save” will be one of the options you have available to you.

If you click on it you are taken to a screen where you just enter the URL of the image you would like to upload and Grab & Save will do the rest. So, now you can upload images directly simply by using their URL.
