Sure can help. It’s not tough to change this section. Of course, you can use revolution slider for it but would be overkill. I would urge you to go through this post and see if it helps. –
It should give you some pointers on it. You can replace the image urls in the code with your own and then see how it looks. Replace – https://www.livemeshthemes.com/appdev/wp-content/uploads/2013/07/featured-app.gif – the main smartphone image with the image of the camera. Then others which are pointers to this image – images with names https://www.livemeshthemes.com/appdev/wp-content/uploads/2013/07/feature-pointer1.png, https://www.livemeshthemes.com/appdev/wp-content/uploads/2013/07/feature-pointer2.png etc. you can replace with links to your own pointers as seen in the above image attached by you.
Once done, if you are still having trouble or need to fine-tune it, Pls reply as a private message here with the site URL and a temporary login to the WordPress dashboard and I can take a look. You may also email me the same (see bottom right box in my profile page). Thanks
