Configure custom image renditions for specific output presets

You can now configure different image renditions for individual output presets under the same output type by using the outputName attribute in renditionmapping.xml. This enhancement gives you greater flexibility when publishing content that requires varying image resolutions for different scenarios. For example, you might want a high-resolution image for your main HTML5 output while using a smaller thumbnail for a lightweight preset.
