The link you have posted is a long winded way of doing what is a simple job as follows:
Open the Program settings, Video/audio tab and set the Imported image length to 1 frame and close the settings dialog.
Select all images to be imported and drag them to the timeline.
You can then make any necessary adjustments as required.

Thank you. Now if they would simply have an option to import images in sequence, I wouldn't have to worry about forgetting to back into the program settings and change it back again.
Fred, you can also change the image length when it/they are already on the timeline: select the image/s you want to change, then right-click and choose "Change photo length".
