One student asked me how to post images in a wiki. I thought others might have the same question, so I'll tell y'all. You just right click (pc) or control+click (apple) on a picture and copy the picture's URL. Then you paste the URL into the wiki. So you're really not putting the picture in the wiki, you're putting the picture's web address in the wiki, and the wiki is smart enough to do the rest. A very few pictures have not showed up. If this happens to you, just pick a different picture.
You'll notice on the wiki assignment page, that you need to have an image on each page. I was really hoping everyone would do a screenshot of the technology they are talking about, especially if you're doing a description page. Seeing just explains things better than telling. However, I forgot that you would need to somehow get the screenshot on the internet so you could then put it in the wiki! You could do this, of course, by putting your screenshot on your BYU U-drive space (the part of your U-drive reserved for website stuff), and then it would be on the internet and you could link to it in your wiki.
But I haven't expected you to use your U-drives or anything like that. So disregard my strong counsel to use screenshots and just use any images you can get off the internet that will help us see what the technology is that you are describing.
However, if some of you WANT to put your pictures on the U-drive and then put them in a wiki, it'd be cool. Once you knew how to put picture on your U-drive you'd be able to put pictures in your blog too. Here's a tutorial to help you do it (it's not hard) and the lab assistants in the McKay building are very good and could probably help you with this.
