Scroll down to the Images folder, and select select sub-folder "frontpage_icons." 

 

If you highlight the resulting graphic names, you can see a thumbnail of what the image will look like at the bottom.  For tutorial purposes, I'm assuming we are preparing a sermon article and have selected "frontpage_sermon.jpg".

Click the ">>" button to the right.

Select the filename "frontpage_sermon" now appearing in the Content Images pane in the middle.  If you have multiple "mosimage" insertions, you would use the "Up" and "Down" fields to rearrange the order, here as we are using only one image we will move on to the next step.

In the column to the right, select "left" from the align drop-down.

For the border field, type in "1"

Until now you were in the Images tab, which is the first tab at the bottom.  Select the Publishing tab, which is the tab to the right of it.  If you don't have this tab, you may not be a Publisher. 

 

Change state to "Published"

For Access level, make sure status is at "Public" if for everyone, or for "Special" if just for congregational access.

For Show on Front page, check checkbox.
