+# render_convertPngToThumbnail.sh -- This function provides post-rendition to
+# create thumbnails from images produced by centos-art base-rendition.
+# Thumbnails are created in PNG and JPG format for you to decide which
+# is the more appropriate one. When no size is specified, thumbnails
+# are created at 250 pixels width and height is automatically
+# calculated to match the image ratio.
