Idea: preload images

[infabo]

Idea:

Add a preload-parameter to s:image viewhelper. If set, a link-header to preload the image is sent to the client. Idea: https://addyosmani.com/blog/preload-hero-images/

• collect images-to-preload (a registry for example)
• finally add link header(s) for each registered image in a dedicated middleware

That would be awesome.

Good idea! Would support for TYPO3 9 be important for you?

With TYPO3 10 the new AssetCollector could be used to collect the media files that should be preloaded:

I would not drop support for v9 right now.

I wouldn‘t want to drop support entirely, but new features could be v10 only if it made sense and made things easier.
