Following is not a bug it can be considered as an improvement or a feature.
In Magento 1 over long time of use media folder size keep growing and it become too huge.(If there a frequent updates of images).
This happens especially for the website having very large catalog. It becomes difficult to identify the unused images and remove them. As an image can be used for multiple products or on multiple pages.
Is there any road map of any feature which will provide a functionality for optimal handling of images in media folder?
