Why an updated theme not showing in website for two days?

2 days ago, I changed code for my website footer theme, deleted the image for that footer, saved changes, but till today nothing happened.

I tried different pc and phones, cleared cache multiple times, not working.

I host my site in Godaddy via CPanel, its created with concrete5.

@yhw7899 Is the image belong to a block and lives in Global Area?
