This is probably a very basic question, but I cannot figure out to wrap the
text on my webpage around some images that I imported. I placed the cursor at
the beginning of the paragraph and then added the image from my computer. But
then all the copy shifted down so that it starts at the bottom right corner of
the photo. I figure there must be a button on the toolbar for this option, but
there doesn't seem to be. Thanks!

When you are in edit-mode in Contribute drag the image into the paragraph you
want it to float in. Then click right-mouse button and select 'image
properties'. Go to alignment and select the alignment you want.
