Write first for the Educated Layperson (that's hard... suggest the "New Scientist" as a style example).
...then try to do it better and write for the beginner (that's harder)
If an educated layperson can't figure it out by following the wikilinks, then it's too hard.
Yes, we're experts (more or less) but we're writing for a general audience. We could write a clever, concise, deep sentence to explain something...but it's useless if it isn't easy to understand.

Images
To insert an image into an article, edit the article and insert
[[Image:FILENAME.jpg| -- | -- | -- |Caption]]
For example, [[Image:Wiki Fairy.gif|thumb|right|160px|[[Wikipedia:WikiFairy|A Wiki fairy in the wild.]]]] Gives you an image on the right, where the caption is a wiki-link.
To have an image deleted, edit its description page and put
{{deletebecause|redundant to image FOO.jpg}} (but of course you would insert the name of the FOO.jpg image. Everything to the right of the | is comment. )
To go (back) to a redirect page itself (e.g., to change or delete the redirect), click and change the page name (here X_page) in the address bar of your browser. Type it in canonical form, i.e., starting with a capital letter and using underscores for spaces.)
