I've had to change the way attached images are uploaded. We did a kludge before that made some things work ok while it broke other things. If you upload an image from your computer or from a URL and have "Retrieve remote file and reference locally" selected, you will see a small thumbnail of the image (assuming your editor is in WYSIWYG mode). While still in the editor, double click on the image and you will get some options. If you would like to see that image displayed larger, change size from thumbnail to medium, large, or full size. Currently thumbnail = 150px, medium = 300px, and large = 640px Most likely you will want "large" which is set to the size we've used in recent years. After saving your post, clicking on the image will still bring you to a full sized version. So this adds an extra step to what you're probably used to, but this is actually the way it's supposed to work. It can be a little clunky, but will hopefully work most of the time.
