As for the article icons.
1. I noticed that the upload limit is hard-coded to 180Kb (even though the text says it is 500Kb).
2. When uploading an image it creates a thumbnail of 128 x 128 (a value we are not using anywhere)
3. The original image is stored in the folder too, but not used anywhere
I am thinking to
1. add a setting to the article settings to allow the admin to set it's own file size
2. add a setting for the icon thumbnail
3. See if we can delete the original images since all they do is take up space...
