This template creates a box with two to ten images arranged vertically or horizontally with captions for the entire box and/or for each images.

Usage

align defaults to "right"
direction defaults to "horizontal"
header_align defaults to "center"
footer_align defaults to "left"
image1 is name of first image. Similarly for image2, etc.
width1 is width of first image. Similarly for width2, etc.
- width overrides width1, width2, width3, etc. If you want the images to be different sizes, do not provide the width parameter.
alt1 is alt text of first image (see WP:ALT). Similarly for alt2, etc.
caption1 is caption of first image. Similarly for caption2, etc.
link1 is where the first page links to. Similarly for link2, etc. If not specified, image links to the image description page as usual. If specified to the empty value, the image does not link anywhere; this should be used for purely decorative images as per WP:ALT.
Important: If the image is under a free license like the GFDL or a CC license, you must not use this parameter as the terms of those licenses require the license, or a link to it, to be reproduced with the image. The image must, therefore, link to its image page. Public domain and (theoretically) fair use images are not subject to this restriction.
background color defines the background color between the border of the box and the images.
header, footer, background color and captions are optional.

Examples

Players are cautioned with a yellow card and sent off with a red card.

{{multiple image
| footer    = Players are cautioned with a yellow card and sent off with a red card.
| width     = 60

| image1    = Yellow card.svg
| alt1      = Yellow cartouche

| image2    = Red card.svg
| alt2      = Red cartouche

When a user has many of one type of barnstar,

they can represent them with ribbons

and these numerals to indicate the count.

{{multiple image
| footer   = When a user has many of one type of [[WP:BARN|barnstar]],
they can represent them with [[WP:RIBBON|ribbons]]
and these numerals to indicate the count.
| width    = 60

| image1   = Ribbon numeral 2.png
| alt1     = 2

| image2   = Ribbon numeral 3.png
| alt2     = 3

| image3   = Ribbon numeral 4.png
| alt3     = 4
}}

Example with background color

Adoxa (Adoxa moschatellina)

{{multiple image
| image1=Adoxa_moschatellina_210406.jpg
| alt1=Green herb with a few tiny yellow-white flowers

| image2=Adoxa_moschatellina_210406a.jpg
| alt2=Three small white and yellow flowers before green-leaf background

| image3=adoxa_moschatellina_blatt.jpeg
| alt3=Leaves of a plant. They are in groups of three, each with three lobes.

| footer=[[Adoxa]] (''Adoxa moschatellina'')
| footer_background=#BBDD99
| background color=#BBDD99
| footer_align=center
| width=160
}}

Example with links

A mule
骡子, luózi

A donkey
驴子, lǘzi

A fish
鱼, yú

The mule links to Mule, the donkey does not link anywhere, and the trout links to its image description page as usual.

{{multiple image
| footer    = The mule links to ''[[Mule]]'', the donkey does not link anywhere, and the trout links to its image description page as usual.
| align     = left

| image1    = Frecklesmule.jpg
| width1    = 143
| alt1      = A mule
| caption1  = <center>A mule<br />骡子, ''luózi''</center>
| link1     = Mule

| image2    = Donkey in Clovelly, North Devon, England.jpg
| width2    = 150
| alt2      = A donkey
| caption2  = <center>A donkey<br />驴子, lǘzi</center>
| link2     =

| image3    = Rainbow_trout.png
| width3    = 91
| alt3      = A trout
| caption3  = <center>A fish<br />
{{lang|zh|2=鱼}}, ''yú''</center>

Horizontal placement: matching image heights

This trick is not required if all images have the same aspect ratio, where |width= suffices

Decide on a common height for the images, say 100 pixels.
Examine the individual image pages to obtain the full resolution. For example:
- File:Donkey in Clovelly, North Devon, England.jpg shows "Donkey in Clovelly, North Devon, England.jpg‎ (750 × 536 pixels, file size: 125 KB, MIME type: image/jpeg)"
- File:Rainbow trout.png shows "Rainbow_trout.png‎ (300 × 300 pixels, file size: 158 KB, MIME type: image/png)"
For non-square images, use these figures to construct an expression for the |widthn= parameters, of the form:
- {{#expr: (dh * ow / oh) round 0}}
where
- dh is the desired height in pixels (100)
- ow is the original width in pixels (750 or 300)
- oh is the original height in pixels (536 or 300)
For square images, simply set the appropriate |widthn= to be the desired height. If all are square, only |width= needs to be set.

A donkey, not square and originally 536 pixels high

A fish, square and originally 300 pixels high

The two images are both rendered 100 pixels high

{{multiple image
| footer    = The two images are both rendered 100 pixels high
| align     = right

| image1    = Donkey in Clovelly, North Devon, England.jpg
| width1    = {{#expr: (100 * 750 / 536) round 0}}
| alt1      = A donkey
| caption1  = A donkey, not square and originally 536 pixels high

| image2    = Rainbow_trout.png
| width2    = 100
| alt2      = A trout
| caption2  = A fish, square and originally 300 pixels high
