while working on "view" I get the problem that in toolset (see -> toolset.jpg) my images are centered while on the web they are not (see -> web_page.jpg)
Is there any documentation that you are following?
The image alignment is being affected by some additional CSS added to the page which sets the image width to 100%. I'm not sure where exactly the CSS is added, but you can see the relevant style rule in the screenshot.
