In "compose" mode (not HTML, select this on the upper left of the edit post screen) you should be able to click on the image. An bar will appear below the image with several options for size, location, and caption. Select center then click off the image and it should work.
I may have to get back to you next time I post a photo. The old computer used to have a number of "buttons" in the screen I used to download pix for Blogger, but this one seemed to give me a big empty box. I may have missed something, but in the insomniac middle of the night I will wait!
