[edit] Uploading
You can upload JPG files for use in illustrating your articles. To upload, click on the Upload file link in the toolbox that is at the left side of all Wiki pages. In the upload dialog, in the Source filename space, fill in the name of the file on your PC that you want to upload; in the Destination filename space fill in the name that you want the file to have on this Wiki; and in the Summary space provide a brief description of the image. Wiki markup is supported in the summary.
By uploading an image to this Wiki, you agree that the image may be freely used by anyone. Upload only images that you have created yourself, or whose creator has given you permission to upload here.
Please edit photos before uploading them. Crop them appropriately, and also reduce the size to a maximum image size of 800x600px and maximum file size of 150Kb unless you have a compelling reason for requiring a large format.
[edit] Guidelines for image use
Use photographs to illustrate information in articles. The Wiki is not a replacement for the CBC photo gallery; please don't simply upload a photograph and make a page for it. If you write an article on the distribution of Cerulean Warblers in the Carolinas, it would be appropriate to include a photograph that you have taken of a Cerulean Warbler, or of Cerulean Warbler habitat. It would not be appropriate just to upload a photo of a Cerulean Warbler and make a page about the photo.
[edit] Placing images in articles
You include an image in an article by using the image tag where you want the image to appear. A typical example of an image tag is
[[image:image name|thumb|caption]]
where image name is the name that you entered as the Destination filename, and caption is the caption that will appear with the image. Important: image names are case-sensitive. If you named your image Black Rail.JPG then referring to it as black rail.jpg will not work. Also note that in the file name, spaces will be replaced with underscores, e.g. Black_Rail.JPG; use spaces not underscores in image tags.
More advanced features of the image tag are described at Wikipedia:Images and Wikipedia:extended image syntax.
Here are some illustrations of uses of the image tag.
[edit] Thumbnail example (right)
This is an example of a photograph that is near the maximum suggested size. The image tag uses the thumb keyword so the image is displayed in a small "thumbnail" size but clicking anywhere on the image within the thumbnail or on the "enlarge" icon below the image will display the image's upload page, which includes the full-size image, the description that was supplied at upload time, and the upload history. Note that the thumbnail is displayed within a box, and that the caption information included in the image tag is displayed within the box and below the image. Note that by default the thumbnail is displayed at the right side of the screen.
The tag used for this image looks like
[[image:Northern Mockingbird large example.jpg|thumb|Northern Mockingbird, Butner Gamelands, 3 Dec 2006]]
[edit] Thumbnail example (left)
This is an example using the same photograph showing how the left keyword can be added to the image tag so that the image is displayed at the left side of the screen. Except for the placement at the left, everything about this example is identical to the previous example.
The tag used for this image looks like
[[image:Northern Mockingbird large example.jpg|thumb|left|Northern Mockingbird, Butner Gamelands, 3 Dec 2006]]
The size of these thumbnails is unspecified and therefore they are displayed at the width specified in your user preferences. Your original preference is 180px until you change it.
[edit] Full size example
It's not a requirement to use a thumbnail. You can instead size the image to be the exact size that you want, and use that image directly in your article. Simply omit the thumb keyword from your image tag. Here's an example; it uses a copy of the same photo that was edited to size of 300x225px before being uploaded, and displays the photo at that size.
The tag for this image looks like
[[image:Northern Mockingbird small example.jpg|none|Northern Mockingbird, Butner Gamelands, 3 Dec 2006]]
Clicking on this image works the same as clicking on a thumbnail, but note that the image shown after the click is the same size as the one in the article.
This photo is displayed without an enclosing box, or a caption. To get the box and caption; add the frame keyword, as in this example:
The tag for this image looks like
[[image:Northern Mockingbird small example.jpg|none|frame|Northern Mockingbird, Butner Gamelands, 3 Dec 2006]]
Note that an image of this type can be distinguished from a thumbnail by the absence of the "enlarge" icon below the image.
