[Template Bug]: gsl_starter_1_3

### Confirmation

- [x] I have confirmed this is a workflow template mistake

### Template Name

gsl_starter_1_3

### Problem Description

the image needed for gsl_starter_1_3 (car and landscape is not included and no note on where to obtain / or to generate )

### ComfyUI Mode

Legacy Mode

### Error Message / Logs

```text
no logs, just workflow not complete without the image
```

Start by locating the gsl_starter_1_3 workflow template and inspect how its image inputs are represented in Legacy Mode. Confirm which car-and-landscape image is required, then make the template complete by including it or documenting where to obtain or generate it; verify that the workflow no longer depends on an unexplained missing image.
