Bird, thank you! But no, although I do see the drop-down option, now that you've mentioned it (I won't use it, thank you!), the one I've been using is the "new post" button on the toolbar that appears at the top of the page when I'm logged in. When I use this button, the white border that otherwise shows up around my image is not added, but the text does appear below the image (though a hard return automatically adds a line of air...frustrating...I'm glad I'm not posting poetry!)
Alternatively, when I go to the page that lists all of my posts with options for managing them, there is a button "Add New." When I use it, all of my text gets squeezed into the tiny space to the right of my image (I need it to appear below the image). When I started the blog (in 10/12), there didn't seem to be so many options for creating a new post, and the one I used automatically added the white border (I assumed this was just part of the theme) AND put the text below the image.
I'm wondering if there's anything I can do using this latter ("Posts-->Add New") option to get the text to stop wrapping (or whatever it's doing), but keep the white border. I never touch the coding in either option (all I know how to do is add a hard break :-)), so I don't think it's anything I'm doing, but wondering if I can fix it nevertheless....Sorry to be so long-winded. This is hard to explain without the visual.
Thanks for your reply! Any other thoughts are most welcome!
