Your images is OFF-TOPIC this will not help your post more attractive instead it really hurts my eyes because the text became smaller due to the unrelated images.
Images definitely can't be off--topic,only content can, and one thing that definitely isn't off-topic is OP's content,i doubt you read the whole article(just my instinct)
This is surely a guide that could help one or two people learn, brush up their English and earn merits easily..
The photos/images may not be helpful to the content of the article,but It sure doesn't/didnt make the article any less worthwhile or quality
