Help:Images
From RebirthRO Wiki
This page explains the image syntax when editing the wiki. You or another user must usually upload an image before you can use it on a page.

Syntax
The full syntax for displaying an image is:
[[File:{file_name}|{options}]]
Where options can be zero or more of the following, separated by pipes:
- border, frame, thumb, or frameless: Controls how the image is formatted
- left, right, center, none: Controls the alignment of the image within a text
- baseline, sub, super, top, text-top, middle, bottom, text-bottom: Controls the vertical alignment of the image within a text
- {width} px: Resizes the image to the given width in pixels
- {width}x{height}px: Resizes the image to fit within the given width and height in pixels; it is possible to specify only the height by writing x{height}px
- Note that the image will always retain its aspect ratio.
- link={destination}: Allows to link to an arbitrary title, URL or just nowhere.
- link= : Will display an image without link, e.g.
[[File:Example.jpg|20px|link=Help:Images]]?
.
- Note that link cannot be used in conjunction with thumb as thumb is always meant to link to the larger version of the image. In addition, link cannot be used with frame.
- link= : Will display an image without link, e.g.
- alt={alternative text}: For changing the alternative text (alt="") of an image.
- Special cases:
- page=1: Displays the specified page when showing a djvu or pdf file
The options can be given in any order. If the given options conflict each other, the latter is applied, except for the format options, where the options take the priority in the order of frame, thumb, and frameless and/or border.
If a given option does not match any of the other possibilities, it is assumed to be the caption text. Caption text can contain wiki links or other formatting. If no caption text is supplied a caption is automatically created showing the file name; to completely remove the caption, set it to <span title=""></span>. For example, [[File:Example.jpg|20px|<span title=""></span>]] ? 
.

When the height of an image in thumbnail is bigger than its width and you find it too outstanding, you may try the option upright, which will try to adjust its size to more desirable size.
Note that by writing thumb={filename}, you can use a different image for the thumbnail.
Alignment
Note that when using frame or thumb, the default alignment will be right.

|---|---|---|
| specify alignment as none |

Size and Frame
Among different formats, the effect of the size parameter may be different, as shown below.
- When the format is not specified, or only
bordered, the size can be both reduced and enlarged. - An image with
framealways ignores the size specification. - The size of an image with
thumbandframelesscan be reduced, but can not be enlarged beyond the original size of the image.
For how it appears when its size is not specified, see Format section above.
| Format | Reduced | Enlarged |
|---|---|---|
[[File:image_sample| |frame|50px]]
|
[[File:image_sample|frame|500px]]
| |
| border |
[[File:image_sample|border |frame|50px]]
|
[[File:image_sample|frame|500px]]
|
| frame |
[[File:image_sample|frame |frame|50px]] |
[[File:image_sample|frame|500px]]
|
| thumb |
[[File:image_sample|thumb |frame|50px]] |
[[File:image_sample|frame|500px]]
|
| frameless |
[[File:image_sample|frameless |frame|50px]]
|
[[File:image_sample|frame|500px]]

Stopping text flow
On occasion it is desirable to stop text from flowing around an image. Depending on the web browser's screen resolution and such, text flow on the right side of an image may cause a section header (for instance, == My Header ==) to appear to the right of the image, instead of below it, as a user may expect. The text flow can be stopped by placing <br style="clear: both" /> before the text that should start after the image.
Gallery of images
It's easy to make a gallery of thumbnails only, not other images, with the <gallery> tag. The syntax is:
<gallery>
File:Image Name.ext|caption
File:Image Name.ext|caption
{...}
</gallery>
Note that the image code is not enclosed in brackets when enclosed in gallery tags.
Captions are optional, and may contain wiki links or other formatting.
for example:
<gallery>
File:Example.jpg|Item 1
File:Example.jpg|a link to [[Help:Contents]]
File:Example.jpg
File:Example.jpg
File:Example.jpg| ''italic caption''
File:Example.jpg|on page "{{PAGENAME}}"
</gallery>
is formatted as:
Item 1 |
a link to Help:Contents |
|
|
italic caption |
on page "Images" |
Parameters
The gallery tag itself takes several additional parameters:
<gallery {parameters}>
{images}
</gallery>
-
caption={caption}: sets a caption on the gallery. -
widths={width}px: sets the widths of the images. Note the plural, widths -
heights={heights}px: sets the (max) heights of the images. -
perrow={integer}: sets the number of images per row.
Example:
Coding:
<gallery widths=60px heights=60px perrow=7 caption="sunflowers are groovy"> File:Example.jpg File:Example.jpg File:Example.jpg File:Example.jpg File:Example.jpg File:Example.jpg File:Example.jpg File:Example.jpg File:Example.jpg File:Example.jpg </gallery>

Links
Link to description page
If you put a colon (:) before File:, the image will not be embedded and the link will lead to the description page of the file.
[[:File:Example.jpg]] [[:File:Example.jpg|Sunflowers]]
results in
Link to an other page
This will make a 50px width picture with a link to the page MediaWiki:
[[File:Example..jpg|50px|link=MediaWiki]]
Link directly to file
You can use the pseudo-namespace “Media” to link directly to a file, bypassing the description page.
[[Media:Example.jpg]] [[Media:Example.jpg|Sunflowers]]
results in
You can also use:
[[Special:FilePath/Example]]
which can be used to link to a potential file, even if it doesn't exist. You can also use:
{{FILEPATH:Example}}
which generates an external URL to the file inline:
Requisites
Before using images in your page, the system administrator of your wiki must have enabled file uploads and a user has to upload the file. System administrators may also set the wiki to accept files from foreign repositories, such as the Wikimedia Commons. For server side image resizing it is necessary to have a scaler configured (such as GD2, ImageMagick, etc.).
