For example this is an example of code to be inserted
<object width="600" height="450"> <param name="flashvars" value="offsite=true&lang=fr-fr&page_show_url=%2Fphotos%2Fmuseumdetoulouse%2Ftags%2Fchantierexpoeau%2Fshow%2F&page_show_back_url=%2Fphotos%2Fmuseumdetoulouse%2Ftags%2Fchantierexpoeau%2F&user_id=8600713@N05&tags=chantierexpoeau&jump_to=&start_index="></param> <param name="movie" value="http://www.flickr.com/apps/slideshow/show.swf?v=109615"></param> <param name="allowFullScreen" value="true"></param><embed type="application/x-shockwave-flash" src="http://www.flickr.com/apps/slideshow/show.swf?v=109615" allowFullScreen="true" flashvars="offsite=true&lang=fr-fr&page_show_url=%2Fphotos%2Fmuseumdetoulouse%2Ftags%2Fchantierexpoeau%2Fshow%2F&page_show_back_url=%2Fphotos%2Fmuseumdetoulouse%2Ftags%2Fchantierexpoeau%2F&user_id=8600713@N05&tags=chantierexpoeau&jump_to=&start_index=" width="600" height="450"></embed></object>

It could be nice to have something like the youtube to help users to build a Flickr Gallery. It could be nice to have a tool to help the contributor to keep aspect ratio on the size.
