If you are using images embedded in text, as bullets, or as other ancillary devices, generally this outlining looks awful. Whether or not you want it, some of your readers will be children or from countries with differing moral standards that yours. Try hard to avoid sexual reference, profanity, or other devices inappropriate for such readers. If you must use them, please indicate that such will follow. People like interaction.
Some constructions look awful if broken across lines.
My version of Netscape has a funny bug. It won't vertically align images at the beginning of a line of text correctly. Use speech affectations only when you expressly intend to. More importantly, these constructions can confuse the reader. Omit anything needless.
