Uploading images to a Wiki might seem like a simple operation, but there are a few tricks to remember.
You need to have your images uploaded to an image library on SharePoint.
You will need to provide the path for that image, so grab the path before you navigate to your wiki to add.
It works best if the name of your image library is one word, not separated by underscores or spaces. So "Images1" is better than "Images for my wiki."
Once you have created the image library for the images that you want in your wiki, navigate to your wiki page and click the image icon.
You'll be asked to provide alternate text and the URL. Use the full path to your image, which will be something like 'http://sharepoint/sites/<site name>/<name of image library>/<name of image>.jpg. It will vary depending on how your administrator has set up the original path (the stuff before <site name>). Confused about the path to your image? You can view the path by right clicking on the image and selecting Properties. There may be extra characters in there. Ignore them, those _t's and others.
