I don’t know how to show you the image as it appears before posting it on the blog.
I’ve tried a few suggestion found on previous posts here. I’ve tried resizing on photoshop to 450px width. i’ve tried changing the values in size row to nothing. Neither of those things change the image at all.
We can see the originals by checking the source code of your page and getting the image URLs. But we needn’t – it’s a known issue. Upload images no wider than 444px, and remove the width and height commands from the image code.
