Today, there is no way to include a picture gallery in a post. It would be fine to include an interactive picture gallery feature gallery.
I've quickly tested the online demos of the following free Flash-based solutions:[list]
[url=http://www.airtightinteractive.com/projects/postcardviewer/]Postcard Viewer[/url]: PostcardViewer is a free Flash image viewer.
[url=http://www.airtightinteractive.com/simpleviewer/]SimpleViewer[/url]: SimpleViewer is a free, customizable Flash image viewing application.

[url=http://www.webworksite.com/photogallery.shtml]FREE Photo Gallery v.2[/url] (linkware)[/list:u]There are other commercial solutions that might be interesting to support:[list][*]Adobe Photoshop CS2 Flash Web Photo Gallery
[url=http://www.slideshowpro.net/]SlideShowPro[/url]: Photo Gallery and Slide Show Compotent for Flash MX 2004[/list:u]Here are some ideas about implementing such a plug-in or hack:[list][*]add a Toolbar Plug-in in order to add the right additional tags to the currently edited post and select the pictures to show together as well as the software used for the presentation;
add a Renderer Plug-in in order to convert the post contained tag to the final interactive gallery form.[/list:u]Interesting features would be to:[list][*]easy installation:[list][*]automatic installation;[*]automatic interactive gallery solution detection;[*]plug-in(s) preferred;[/list:u][*]full documentation (including online contextual help);
support for several (most/all?) popular interactive galleries solutions;
[*]default interactive gallery solution included.[/list:u]
