Thank you, Jeffw!
I followed your link and got a new code and it worked!
Now, everything is just fine. But, there is still one more little thing left to fix. The matter is the previous code had a “caption”, so my pictures looked beautiful with it. Now, sinse I’ve applied the new code, my pictures don’t have captions. Here is the old code with caption: [caption id="attachment_267"... [/caption], and here is the new one: [styled_image w="300" h="200" lightbox="yes" align="left" rel="styled-1" alt="Plaza Beach Resort Bonaire" image="267"]. I have tried hard to combine them together but got to nothing. Please, helpI if this is possible?
