Get image size before upload

[true flicker]

Is there a way to get the size of a image before it is published with the publish function?

I would need this to trake uploaded date per build and user that initiated the build.

[proper lark]

there's not a specific API for this, but you can call container.AsTarball, put the image into a .tar file and check the size there

this will be the uncompressed size but will give you a baseline to measure size changes
