How to send Akamai cache expiration headers?
I have a site where each time you upload an image it gets rendered in various frame sizes. A cron job runs every 10 minutes which looks to see if any new images have been uploaded during that time and if so it generates all the needed frames.

Since this cron runs every 10 minutes there is some time between the content (such as an article) goes live and the time the images are made available. So during that meantime a generic placeholder image with the site's logo is shown.

Since Akamai caches an image, when a site user loads a page which has an image that hasn't been rendered by the cron yet, then a static placeholder will show for that image path and Akamai will cache this. Even when the image is later rendered and is available users will still get the cached version from Akamai.

One solution is to bust the "ages" of these images when the cron has rendered them. But it takes Akamai about 8 min to come back for the new ones. 

Is there any other solution where I can tell Akamai perhaps through cache expiration headers to come back every 10 seconds until a new image is received and once that's done don't come back again and keep showing the cached version?
