Certain Blogger glitches have been driving me nuts.
-The new photo editor, as far as I know, does not let you adjust the size of the photo manually. Sometimes I choose "small," but there is no way to to click and drag at the corners to make it even smaller or to get a custom size in between the prescribed "small" and "medium."
-Photos sometimes upload sideways. If this has happened to you I'm sure you understand how aggravating it can be. They blame it on a Canon incompatibility, blah blah blah. I experimented with some file formats in Paint, and .PNG seems to fix the sideways problem. You can do your editing elsewhere and then just open the file in Paint and save it with the new extension. I'm sure there is probably a more sophisticated way to do it, but this works for me. :)
