When you add a photo to your post there are several steps documented on the help page How to Create a Post and in the pdf documentation “Daffnet User Guide Comments and Posts” we emailed to many of you yesterday.
This is just an additional note about how to make sure your photo “zoom or enlarge” when someone mouse-clicks the image. When you are inserting a photo into your post, you will see a screen similar to the attached photo. Just make sure you have clicked the “File URL” button to the right of the menu item “Link URL”. This attached image shows a mouse cursor or “hand” under the button that should always be selected.
The is the forum default, but if you change this setting, remember the “File URL” choice displays photos best. This is not a critical setting, it simply improves your post display.
