Writing topic problems

After you put in the image, press return only once and see if that does it.

What browser are you using?

For your previous question: it is certainly better to disable the wysiwyg. If you just type in it, it might work decently. But as soon as you try formatting and more complicated stuff… it screws up everything.
You can/should disable it in two places:
a) for the whole blog > Options > Writing
b) for yourself > Users > Your profile > bottom left corner

is there no way of formatting and doing more complicated stuff in posts with good results then?

Anyone can format a post or page to whatever degree of difficulty they can imagine, and then probably times that by 100.

Formating and doing “more complicated stuff” without the use of WYSIWYG is done through CSS/HTML. Best place to start is reading up on both. There’s a billion sites out there offering tutorials and step by step guides on how to do all sorts of wonderful things.

My fav site is mandarindesign.com/boxes.html

I’ve found that combining the RTE with CSS works really well. For example, using a plugin to activate a couple of TinyMCE’s feature’s (that WP has deactivated for some reason) can go a long way. Specifically the two select dropdowns (“format” and “style”). I put some css to handle images and h1-h6 in the worpress.css file (and style.css) located in the TinyMCE folder in the wp-admin directory. Now when I want to right justify (float) an image so the text wraps I click on the image and then hit the “style” dropdown and select “imgright”. It would be great if the wordpress.css file was accessible in the “presentation” section of the site admin so it would be easier to alter. I know XHTML pretty well but I find it valuable to be able to do everything I want with the RTE.
