Yes, the pictures are.

AC vs DC markings:


1A = 1000mA

Tip/Ring polarity markings - note how #1 and #4 are the same, as are #2 and #3 - sometimes they mark the symbols upside down on the power supplies. The important part is the center dot is the "tip" the outer "C" is the "ring".



When you have a barrel connector, the center is always "Tip" the outer sleeve is always "ring". In the photo below, the power supply should be marked with the first or fourth image from the photo above.
