For this activity I used an image I already had uploaded to WordPress. I added it to my blog and then edited the image. In there there’s a feature to change the size of your image to a thumbnail (150 x 150 pixels). If I didn’t see that feature I would have edited my image first to create a thumbnail. Then I linked my thumbnail to the original. I also copied and pasted the code that Keith gave in the lesson to show text when the mouse hovers over the thumbnail.
