This template displays a gallery of images in an array, left-to-right in rows. Global parameters |width= and |height= control the size of all images in the gallery. The number of images per row is based upon the image width parameters and the width of the screen. The number of images per row can change when the user resizes the window.

For style guidelines about where galleries are appropriate, see Wikipedia:Image use policy § Image galleries.

}}

Specify a line of the following form for each image.

|File:Filename |Caption |altn=alternative text

Note that the file name and the caption do not need parameter names, but each alt text parameter must be preceded by |altn=.

Where:

|File:Filename – the image's file name. Either File: or Image: prefix may be used

|Caption – the caption under the image; see Wikipedia:Manual of Style/Captions

|altn= – alt attribute: |alt1= for the first image, |alt2= for the second image, etc

alternative text – the alternative text for the image, used by visually impaired or other readers who cannot see the image clearly. If omitted, the image's alt text will be blank.

These parameters apply to the entire gallery:

|title= – The gallery's title

|align= – The alignment of the gallery on the page, left (default), center, or right; ignored when |state= is set

|footer= – Small, right-aligned text below the images

|style= – CSS style directives for the whole gallery (see Help:Cascading Style Sheets)

|state= – Sets the default state of collapsible galleries; use |state=expanded or |state=collapsed; collapsible galleries occupy the full page width

|mode= – Sets the mode used by the inner gallery tag. Common values include |mode=packed and |mode=nolines (see Help:Gallery tag for more options)

These parameters apply to all of the images in the gallery:

|noborder= – Cancel the border surrounding the images, use |noborder=yes to set.

|whitebg= – Cancel the white background after the images, use |whitebg=no to set.

|height= – Maximum height of each image. If this parameter is not included, |height= defaults to 180 pixels. Use a simple number here, e.g., 200, without a units designation, e.g., 200px.

|width= – Maximum width of each image, default is 180 pixels. Use a number here, e.g., 150, without units, e.g., 150px.

|perrow= – Number of images to display per row

|captionstyle= – CSS style directives for the captions (see Help:Cascading Style Sheets)

The image's original ratio of width to height cannot be modified by |width= or |height= – a rectangular image will not be made square if |width= and |height= are set to the same value.
