Well, some tallented guy has created a plugin to insert image from RSGallery2 into content(articles). I want to push this project one step forward: could you please make it possible to insert image from RSGallery2 into JoomlaBoard forum post ?

You know sometimes we want to paste more pictures into forum post if that is a forum about picture or camera or tourism, etc. But at the same time we may allow users to set up their own album/gallery. So If they can insert images from their own gallery by this plugin into JoomlaBoard forum post, it will make discussion more easy.

Thanks.

Yes, I also understand a plugin for com_content can't work with other component. How about develop a new plugin for JoomlaBoard or SMF or other forum program. So members can "cite" images in their personal gallery ?

It's nothing about stupid or clever, it is about your imagination.
