+Feature: #59591 - Image quality definable per sourceCollection
+==============================================================
+
+See :issue:`59591`
+
+Description
+===========
+
+The image quality of each `sourceCollection` entry can be configured.
+Integrators can already render images with the predefined quality set by LocalConfiguration.php.
+To decrease the quality of larger images (e.g. double density) in order to lower the file size,
+integrators can configure the parameter `quality` of the matching `sourceCollection` now.
+
+The TypoScript setup can be configured as followed (e.g.):
+
+.. code-block:: typoscript
+
+	# for small retina images
+	tt_content.image.20.1.sourceCollection.smallRetina.quality = 80
+
+	# for large retina images
+	tt_content.image.20.1.sourceCollection.largeRetina.quality = 65
+
+If the new parameter is not set, TYPO3 will use to the default quality of LocalConfiguration.
+
+
+Impact
+======
+
+The rendering of `sourceCollection` stays as it is. Users can additionally selectively control the quality of jpeg by TypoScript setup.
