This image is for Signpost images. Usage is documented at {{Signpost draft helper}}, along with other such templates. Here is the section of that template pertaining to images:
To put an image in your article, use the following code
[[File:|center|300px|alt=Placeholder alt text]]
CAPTION
{{Wikipedia:Wikipedia Signpost/Templates/Filler image-v2
|image=
|size=300px
|alt=Placeholder alt text
|caption=CAPTION
|fullwidth=no}}
This will create the file on the right. Keep the 300px in most cases. If writing a 'full width' article, change |fullwidth=no
to|fullwidth=yes
.
Placing
{{Wikipedia:Wikipedia Signpost/Templates/Inline image
|image=
|size=300px
|align=center
|alt=Placeholder alt text
|caption=CAPTION
}}
will instead create an inline image like below
You can add the capcenter
parameter to make the caption box centered (do this if you want it to be centered on a fullwidth page; it sets the div of the caption to margin: 0 auto
.)
