Mixed Content = No Green padlock – SSL

Hi guys. I have moderate experience with wordpress. I have successfully installed your theme, and I am editing it to my needs. However when I installed the ssl certificate I noticed there is no green padlock in the link bar.
I then did a test on whynopadlock.com ( here is the link with the test results : https://www.whynopadlock.com/results/3c7eea09-a8fe-497e-97d3-2f56f26c3dad )

It seems that 2 images are causing the error since the images are hosted on HTTP instead of HTTPS, however the issue is, i cannot find where the code is located that is referencing these 2 images. I have deleted the 1.jpg image completely from my website and it doesnt exist anymore, however for some reason website is still referencing it , and the error persists.

The second image background.png I have reuploaded and it is indeed https now , however the website is still referencing the http file when I check for mixed content in google chrome inspect element tab.

My website is : https://www.baldybaldy.com

Most likely there is an external javascript thats referencing these 2 images or something, as stated on the test result from whynopadlock.com , however I do not know where this javascript file is.

I tried using all possible plugins to change all http files to https but nothing helps, I tried more than 10 different plugins for SSL optimization and for http to https change, but nothing helped. I also tried to search the complete database ( database search plugin ) to see where the http file is referenced however the search returned nothing.

I have also tried disabling ALL plugins I have installed in hopes that one of the plugins is causing the error, however problem is still the same, so that means that the issue is coming from the theme itself.

Can anyone help or give advice on how to find the 2 lines of code where those 2 images are referenced and change them to https , or completely delete those lines of code? Thanks again!
