Dev1 : hey dude, I am not able to get the slider right like the one in the IMG they've created on WordPress, we need to show this to the client today. Can you help?

Dev2 (short for devil) :
*Tries*
*Sighs*
*Opens up expected screen slider IMG*
*Ctrl + Alt + Printscrn*
*opens Paint ---> crop --> save*
*Inside html, <img src="*above url">*
