Terribly sorry for taking so long to respond to your question. I wanted to try to apply the instructions to publishing new posts which hasn'nt been successful. I really appreciate Timethief’s references provided to help me, but when I look at the bottom of my HTML text editor window I don’t see the excerpt box below the editor box she mentions unless it is a widget that I haven’t activated yet. The ability to do this is very important for me; I’d like to publish a post today and if you have any further clarification on the subject I’d welcome it.
The upload/insert dialog box allows option to designate which image to uses as featured post image, and then doing so, the option is presented to place the image. If I only designate the featured image is shows up at bottom of right sidebar w/o codes, until or if I place the image. Placing the image, I then see HTML code for the image; the image also shows up on all other posts subsequently published instead of that specific post.
In the tags gallery I always see full images placed in the image area and text only appear in the image if you mouse-over the image. That’s what I’m trying to achieve.
