Edits to wiki page not taking effect.

For background, I have enough points to edit pages without requiring a moderator's approval. I came across the Paul Luther page, which when I first saw it, wasn't displaying the images that had been placed in the article correctly. I opened the editor, fixed the images by changing their sizes and changing them back, and then made some edits to clean up the grammar a bit before submitting. After the submit, however, the only change that took was the fixed images. The text didn't change. I tried to edit the text a second time and it still didn't appear to work. I have also tried refreshing the page, but that doesn't show any sign of change, either.
