Help:Images
From Environment & Energy Wiki
Images may be added into articles. They take up database space so I ask that members add them only where they are a useful part of the article and not just for decoration. I also ask that the file size be kept as small as possible. Please keep the longest dimension to 640 pixels, less if possible.
Do not use images that are copyright without the owner's permission and indicate the copyright owner and date. Note that some government images are in the public domain (e.g., those in US .gov sites) and may be used, but it is courteous to cite the source. Other governmental images may be copyright but with tacit permission to copy for non-commercial purposes, provided they are accompanied by a copyright notice (e.g., Environment Canada). An example of each can be seen in the Landfills article.
Format
Photographs are best kept in .JPG format, with as much compression as possible, consistent with clarity. If possible, aim for a file size of less than 50 kb or even less. Line diagrams and charts should be in .GIF format with 16 colours. A very useful freeware (for non-commercial use) tool is FastStone Photo Resizer 2.5[1], which is an image converter/resizer intended to enable users to convert, rename, resize, crop, rotate, change colour depth, add text and watermark to images in a quick and easy batch mode. Some other formats are also supported.
Uploading
Before an image can be incorporated in an article, it must be uploaded into the database. This is easy. Click on Upload file in the toolbox. If you cannot see it, type special:upload in the search box. You will see a window like:
Browse to find the file to upload, adding any text you wish in the summary, then click the Upload button. In a few seconds, you will be taken to a page labelled (in the example) Image:Emedco2.jpg. You may find it useful to select and copy this label - I do!
Putting the image in an article
The general syntax is [[Image:Emedco2.jpg]], still using our example, in its own paragraph (you can add the copyright or source notice, if appropriate on the same line after the double brackets). This places the image at full size within the text body. I find this useful where the image needs much reference within the text. The first image in Landfills is a good example.
If you took my advice and selected/copied the Image:Emedco2.jpg page label in the previous section, all you have to do is to paste it, select it and hit the third icon (underlined Ab) to avoid having to type it out fully.
A second syntax is [[Image:Emedco2.jpg|thumb]]. This puts a clickable thumbnail image to the right of the page. Clicking on it will reveal the full image. This is neater and is useful where the reader is not likely to refer to the image more than once.
