-== Center ==
+== [[Image:Hugin_center_pano.png]] Center ==
 This button horizontally ''pans'' the output, changing the [[yaw]] of the remapped images so they fit to the centre of the output frame.  This is useful if there is a lot of black space on the left or right of the output.  This also performs a '''Fit''', equivalent to the next button.

 Note that centering a [[Rectilinear Projection]] or [[Fisheye Projection]] panorama will change the perspective, this may be unwanted.
-== Fit ==
+== [[Image:Hugin_fit_pano.png]] Fit ==
 This doesn't change any input image parameters, it just readjusts the output [[Field of View]] such that all the input images are visible.  If the images are all off-centre, then there will be a lot of black space.
-== Straighten ==
+== [[Image:Hugin_straighten_pano.png]] Straighten ==
 Straightening the panorama optimises the [[roll]] and [[pitch]] of the input images without changing their relative positions, levelling the panorama in the process.  This normally produces good results, if you need more accurate positioning, try adding [[vertical control points]]
 in the [[hugin Control Points tab]].
-== Num. Transf. ==
+== [[Image:Hugin_preview_num_transform.png]] Num. Transf. ==
 This opens up a pop-up window that allows you to enter a '''numerical transform''' to rotate the input images without changing their relative positions - Effectively this rotates the entire panorama.

 Enter [[roll]], [[pitch]] and [[yaw]] values in degrees, note that you can also realign the panorama by ''left'' and ''right-clicking'' in the preview image itself, though this is not so precise.
-== Auto ==
+== [[Image:Hugin_preview_auto_update.png]] Auto ==
 Setting '''Auto''' will regenerate the preview every time something changes in the project. This can be slow with large preview windows, so you may want to disable '''Auto''' or reduce the size of the window.
-== Update ==
+== [[Image:Hugin_reload.png]] Update ==
 When '''Auto''' is unset, the preview doesn't regenerate when something changes in the project.  Click '''Update''' to force a regeneration manually.

 By default all input images are shown in the preview, however individual images can be enabled and disabled in the
 '''Displayed images''' section.  Use the '''All''' button to return to the default and display all the images.
