Help:Images

From LabVIEW Wiki
Jump to: navigation, search

Before you can embed images into your article you must upload them to the LabVIEW Wiki. The easiest and most convenient way of doing this is to do it after you finish editing the text of your article.

  1. While you are editing the text, just insert the wiki markup that embeds the image. For example: [[Image:Example.jpg|Sunflowers]].
  2. Save or preview your work.
  3. Now look at the image link in the previewed or saved page. You will see that it is RED in colour.
  4. You can now click on the link (in a new browser tab or window) which will bring you to the upload page.
  5. You will notice that the Destination filename: field is already filled in. All you have to do is browse to your image.
  6. If you go back to your original page and do a browser refresh or a new preview, you will see the image linked.

Uploaded files

To use an image or other file which has been uploaded to the wiki, use:

  • [[Image:Example.jpg]]

If you add a pipe (|) and some text after the filename, the text will be used as alternative text for text-only browsers:

  • [[Image:Example.jpg|alternative text]]

If you don't want to display the image, you can link to the file's description page, by adding a colon:

  • [[:Image:Example.jpg]]

To bypass the description page and link directly to a file , use the "Media" pseudo-namespace:

  • [[Media:Example.jpg]]

You can also make piped links if you want some other text to be used:

  • [[:Image:Example.jpg|link text]]
  • [[Media:Example.jpg|link text]]

Advanced options

The full syntax for displaying an image is:

[[Image:{name}|{options}]]

Where options can be zero or more of the following, separated by pipes:

  • thumb, thumbnail, or frame: Controls how the image is formatted
  • left, right, center, none: Controls the alignment of the image on the page
  • {width}px: Resizes the image to the given width in pixels
  • {caption text}

The options can be given in any order. 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.

Gallery of images

It's easy to make a gallery of thumbnails with the <gallery> tag. The syntax is:

<gallery>
Image:{filename}|{caption}
Image:{filename}|{caption}
{...}
</gallery>

Captions are optional, and may contain wiki links or other formatting.

for example:

<gallery>
Image:Example.jpg|Item 1
Image:Example.jpg|a link to [[Help:Contents]]
Image:Example.jpg|70px
Image:Example.jpg
Image:Example.jpg|''italic caption''
</gallery>

is formatted as:

Other files

You can link to an external file using the same syntax used for linking to an external web page. This feature has to be enabled by the admin; in the new releases of MediaWiki its disabled due to security reasons.

  • [http://url.for/some/image.png]

Or with different text:

  • [http://url.for/some/image.png link text here]

If it is enabled on your wiki, you can also embed external images. To do that, simply insert the url:

  • http://url.for/some/image.png
