### Explanation:
1. **Existence Check**: `if ($('.img-acc .accordion').length > 0)` ensures that the code runs only if the `.img-acc .accordion` element is present on the page.
2. **Scoped Code**: The entire logic is inside the `if` block to avoid unnecessary operations when the element doesn’t exist.
3. **jQuery Ready**: The `$(document).ready` ensures the script executes only after the DOM is fully loaded.

This approach prevents errors in the console and unnecessary execution of the script on pages where `.img-acc .accordion` is not present.
