1) Obviously, first you need a photo. I've just gone to google images and found a photo of a young William James, founder of Psychology and the approach called functionalism. That's cool. [**Snap screenshot of James**]
2) When you click on the "insert image' link, you need to first "upload new image" by finding your image using "browse." Upload the photo and specify its size (try pixel width of 250) and where you want the photo to appear (left, right, etc.) I prefer left justified.
3) When the image is uploaded, you will see a stream of html code in your "create entry." Panic not! Preview to check the placement of your photo. If you like what you see, click on save. If you want to continue editing, click on re-edit.
4) SAVE when you are satisfied with your post.
TIP: You can cut the html text and paste it to vary its relationship to the text. For this post, I have pasted the code before the text.
