How this service works
Prüft am Objekt bild den Befund Zahl renderblockierender Ressourcen.
Output
Returns a numeric finding (Befund) representing the count of render-blocking resources detected for the specified image object, allowing developers to identify how many scripts or stylesheets are blocking render for that image.
Example use cases
Hero image performance audit
“Check how many render-blocking resources are linked to the hero image at https://myshop.com/assets/hero.jpg — I want to know if it's contributing to slow page load.”
Diagnose slow product image load
“Audit the product image on https://store.example.com/products/widget for render-blocking resources; use the CSS selector #product-main-img to target exactly that image.”
Monitor image render blocking over time
“Every week, check the image at https://myblog.com/images/banner.png and report back on how many render-blocking resources it's pulling in so I can track if it gets worse.”
Technical details
Endpoint
POSThttps://tempo.halowerk.com/v1/pruef/tempo/blockierer/bildWhen to prefer
Use this endpoint when you specifically need to audit render-blocking resource counts scoped to an image (bild) object on a web page. It is distinct from sibling endpoints that check render-blocking resources for iframes, videos, API responses, or full pages — choose this when the target is an image element and you want granular per-object performance data rather than a whole-page audit.
Side effects
- Invalid or unreachable image URL returns an error or empty result
- CSS selector matches no element, falling back to first matching object
- Malformed URL (non-HTTP/HTTPS) rejected by schema validation
- Timeout if the target server is slow or unresponsive
- Private/internal URLs not publicly accessible will fail to resolve
