I have copied the following instruction verbatim, and would like any
members to contribute to any other ideas about the procedures.
Inserting images with knol
In order to insert an image into your knoll
1)Enter edit mode by clicking on the [Edit] tab on top
2) A toolbar appears on top of your knol. Place your cursor at the
location in the text where you would like the image to be inserted and
click on the [Image] button on this toolbar.
3) You can choose to add images from your computer, or from the web if
you can provide the URL of a particular picture that you have the
rights to use. If there are images that we’ve obtained for your use
from a third party (such as The Cartoon Bank), that option will be
shown here. If you have uploaded pictures to Knol previously, they
will be displayed
4) Select an image by clicking on it, then click [Add Image] to insert
the selected image into your knol.
5) You can now drag the image around and position it the way you want
within your text. Your text should smoothly flow and wrap around the
figure when displacing it.
Tips:
6) * You can resize the image by clicking on it. A blue toolbar
appears on the top (or the bottom) of the figure, and allows you to
select "small", "medium", "large" or "original size"
7) * To delete a picture, click on it and choose "remove" on the
picture toolbar (the blue bar at the bottom (or the top) of the
picture frame.
8) * No matter what size picture you choose when inserting a new
image, your readers will always be able to see the full-size image by
clicking on it.
