Image Upsert Webhook

When I test my webhook, it's not being notified when an Image is uploaded. I'm getting notifications when an item is published and unpublished. Is there a long queue for asset notifications? I tried uploading three new images, and also edited the descriptions.

So, for some a little bit of background. I did some load testing on a preview version of my site, and I felt that it would be better to store my images in an Azure Storage Blob. In part because I would also like to do some image processing to optimize and crop. My plan is to set up an Azure Function that's trigger by a Webhook when an asset is upserted to Kentico's Asset Library. First the image url will be put into an Azure Queue, and then a Function will copy the image to Azure Storage where I will then make copies of different sizes using TinyPNG.
However, none of this can happen without a notification that an image has been upserted. I created a simple test with https://webhook.site and my webhook is notified when content has been published/unpublished, but not when an image is upserted. Is there some setting I'm missing? The alternative would be to create an image upload application and bypass Kentico Cloud for images altogether.
It looks like the upsert is only triggered when a content item is published and uses an image that has never been in a published piece of content before. That's too late in the workflow for what I'm trying to do.
You've unfortunately hit system limitation at this moment, webhooks are indeed triggered only when an action affects published content, so it won't be possible to do it this way at this moment.
There are improvements we're considering for the future, for example manipulating workflow using CM API or extending webhooks functionality to cover working with unpublished content, so your feedback on will certainly help us prioritize. Do you have any other ideas or scenarios that you can think of that would be helpful for your project?
For your particular scenario there is also major feature that we'll roll out soon and that is Responsive Images API (check out our roadmap). This should allow you to manipulate image attributes directly using our API without having to use external service.
