There are a number of ways of adding images to pages.
If you have a Flickr account and have the images on that site please consider using the Flickr link to add images, this will reduce the memory needed for this wiki
Uploading an image from your PC
Adding an image to a page is a two stage process.
First go to the page you want to add the image to.
1. Upload the image
At the bottom of the page you will see a horizontal menu.
One of the choices is File
Click on this
You will be presented with a list of files already attached to the page (if any)
and a link "Upload a file from your computer"
Click on this and you will be presented with a button Select Files
Click on this and a window will pop up which allows you to select images from your computer.
When you click on ok the files will upload
THE FILES WILL NOT BE DISPLAYED ON THE PAGE ONCE THEY ARE UPLOADED
Now we need to display the image on the page.
2. How to display the image on the page
You now need to edit the page
Go to the bottom of page to same menu you just added the files from and chose Edit
You will be presented with the edit box with a number of buttons at the top.
Place the cursor in the text where you want the image to appear
There are two buttons with a green blue/green appearance, if you hover the mouse cursor over the right one it will pop up a little message saying "insert image wizard"
Click on this and you will be presented with a popup window with number of options
Choose Source Type -> Attached file
You will be presented with a list of images that are attached to the page. These should be the same as the images you attached in step 1
Choose the image you want to display
You can also optionally choose how the image is aligned by choosing from the Position menu
Once you have finished click "insert code"
This will insert code to display the image on the page
Once you have finished editing the page click Save and you are done
