I import the image, select either align right or left, and add to the document. Then I go back and edit the image to add a border and maybe some vertical and/or horizontal space. It looks great on the page.
Then I update and preview. Text isn't wrapped, images are sometimes not where they are supposed to be. There is sometimes a large head space at the top of the previewed page.
Any idea what's going on? I am not well versed in html, and I depend on the WP interface to get me where I need to go.
