The previous version worked better....
The new version has the app for uploading the image, and it seems to have some problems. When you upload an image and then try to set the horizontal and vertical, it wrecks the image every time, turning it into a few dozen pixels wide by lots of pixels long.
If you just leave it at the defaults, then click on the image in the text editor, and attempt to resize using the click-and-drag on the corners of the image, it will allow you to resize the image to what you want, but those changes are lost when you post. This used to work wonderfully well in the previous version.
This may all be a browser issue, dunno. But suffice it to say, the previous version of the image upload seemed much more reliable, and the previous version of the image editing within the text editor WORKED, while the current version does not.
