Resize images in AWS S3

Question

I have a PHP REST API that hosts all images in the Amazon S3. I'm looking for a plugin, or trick, to resize the images using GET params. For example:

http://my-bucket.s3.amazon.com/image.jpg?width=300&height=300

I found this plugin, but a member of my team said it is ASP.NET based and doesn't fit to my PHP API project. Should I use a script hosted in EC2 to resize those images? Is there other way? Ideas are welcome.

Thanks!

Answer 1

I suggest setting up your own PHP service to resize images based on the query string values, as you describe. Yes, the PHP service could be hosted on AWS EC2 or another hosting platform. The service would need to receive the query string such as:

http://example.com/images/image.jpg?width=300&height=300

This would need to be configured (perhaps using mod_rewrite [1]) to receive the name of the image (example: 'image.jpg') and pass the query string size values into your PHP script. The script would then find your image on S3, resize it using an image library (such as ImageMagick / PHP GD or PHPThumb [2]) save it (or not) back to S3 and also pass the image data back through on the original request.

I wish you good fortune!
