Hosting images from unsecured servers (travelnow.com)

My application needs to serve images hosted in travelnow.com (ie. this image) but the application only allow images hosted on a secured server (ie. https).

1. What are my options?
2. TravelNow's suggestion is as follows. How do I do this?

   Akamai image servers are not secure. Therefore you are unable to serve any of the image urls with a secure HTTPS URL. If you need to serve an image with HTTPS, you must temporarily save the image to your own secure server. This is suggested only for images to be saved as you use them or need them temporarily on the secure page.

   The hotel images file available from the Affiliate Center provides up to 1.5 million URLs at any time for all properties storing images in the Akamai system. It is not recommended or advised to store all fil开发者_如何学Goes in advance on your own system since properties change and update images frequently.

   Although we are not responsible for the images each property stores on the Akamai system, YOU will be responsible for any customer issues arising from displaying outdated or saved image files on your own pages.

Thanks! Adrian

I see two options:

• There is a way to "tunnel" the image from TravelNow to the client by passing through your server. But that will add latency.
• You can also download all files from TravelNow and put a system in place that refresh your images regularly. The first download will be rather big. But a check to see if an image has changed is rather simple and fast.
