I have those problems with images:
1.I tried adding <map> tags to the html, because I have a picture with a graph, and some parts of the graph need to link to specified places in my blog. But <map> tag is removed. Is there reason for this ? (probably this might be request to to allow map tag)
2.I create new page, upload image, then put it in the wysiwyg view through the click-the-picture options,then I try to see the HTML, and when I return instead of the picture, in the wysiwyg view there is little picture placeholder with the name of the picture in it, and when i get back after that to simple HTML editor, the src attribute is missing from the <img>
