I use a lot of images in my blog. Some of them are in portrait orientation and that makes a bit of a problem when the text isn't long enough to make the next image start under the previous and I align the images to the text. What I would like to do is to be able to put the style <div style="clear:both"></div> before each image starts, so that they appear orderly even on the manuscript page during editing.
I have tried to add this code in the HTML mode, but it is removed as soon as I save the page and then go back to visual mode.
Ideally, I would like to be able to add this as a custom class to appear in the formattign dropdown. Would that be possible or is there some add-on that can solve this for me?
