Ok Huck I have worked out how to put pictures in your journal if they are already online.
You click on the image button, then in between the tags you need to put the image information. You get this by finding the image you want on the net, right clicking, looking at the properties and then copy and paste the image URL.
I think if you want to put one of your own photos in your journal then you need to upload your photos to a website like photobucket.com and then copy and paste the url they give you in between the tags as explained above.
Hope this makes sense.
