There are three ways that come on my mind to control the margins of the images:
- Use the OnClientPasteHtml event of RadEditor to modify the <img> tags inserted via the Image Manager and apply the desired margin and other style properties.
- Use the Properties module and or the Image Options dialog (when you right click over the image) to apply the desired margin.
- Define a global CSS class for images and define in it a default margin for the images in the content area. You can find how to import it in the content area in this live demo: Customize Content Area.
All the best,
