In previous version of alfresco we were able to copy/paste image directly into a Wiki page (e.g. a screenshot, a copied portion of an image from gimp). Now that we are using Alfresco Share 5.1 (and also 5.2), it's not available anymore.
I don't really know how to (re-)enable this feature. I've tried to force the configuration of TinyMCE with "paste_data_images=true", it works on the interface but it's not saved into the database.
Any clue where I should start to look?
