You can set the topic text and image alignment for individual topics using the commands on the Format tab, in the Format Topic group. More options (such as Text and Image alignment) are available from the Format Topic dialog launcher. You can only set these options in Map View.
Select the topic(s).
For text
alignment, on the Format
tab, in the Formatting group,
click the Alignment 
arrow and select
how you want the text aligned within the topic.
For image placement, in the Topics group, click Image Placement to set the options.
You can drag an image inside the topic to change its placement.
On the Format tab, click the Topics dialog launcher.
You can set the Text and Image alignment on the Alignment tab to position images relative to the topic text.
Some experimentation may be required to get just the right "look" for your map - click Apply to see how your settings will look without leaving the dialog.
On any of the tabs, use the Style button if you wish to:
Save as New Style Default: Save all the topic's format settings as the automatic style for topics of the same type at this level. The settings become part of the current map's style. All existing topics at this level assume these attributes (unless they have been individually formatted), as will any new topics you create. You can save these new settings as a Style Template that you can re-use on other maps. You can see these new attributes in the Modify Style view.
Reset to Style Default: Reset the topic to the automatic formatting of the current style.
