### What happened?

I have installed a brand new forge webui from scratch to verify this issue. Basically the extension does not work in the image2image tab specifically. It works in the text2image tab though. This issue is not present in the regular Automatic1111.

### Steps to reproduce the problem

Download faceswaplab extension and attempt to replace a face in the image2image tab.

### What should have happened?

Face is replaced with another face.

### What browsers do you use to access the UI ?

Google Chrome

### Sysinfo

Windows 11, RTX4090, Brand new forge ui installed from scratch with one click installer.

Start at scripts/faceswaplab.py line 201 and scripts/faceswaplab_utils/imgutils.py line 224, where the image2image postprocess calls processing.apply_overlay with four arguments. Reproduce the FaceSwapLab face replacement in image2image and inspect the apply_overlay signature. Done means the face is replaced without the reported TypeError.
