smart preview management, remove preview as inputs
I tested openpose editor.
Please test yourself to see if anything is missing

1. upload original image to controlnet
2. run postprocess to make canny preview
3. close original image
4. postprocess preview image only in controlnet
5. image generate -> doesn't work as controlnet

nice catch. but this seems impossible to fix since gradio does not have callback when image is removed

[lllyasviel]

oh wait. it is possible in newer gradio

[lllyasviel]

unfortunately this cannot be solved as gradio has a bug that Image.clear is broken on the listener

It worked by 'preview as input' in past.
If this feature doesn't necessarily have to be removed, I think it's more convenient to have it.... Because original image having large filesize make web browser slow. So i need to download postprocessed canny image and input it again.
Some people, including myself, might feel this slightly inconvenient.

[lllyasviel]

image size only influence browser speed when uploading images.

LGTM. Thanks for fixing it. Verified that openpose editor still functions as expected.

What bug prompted this change? Was there something not working previously?
Because there obviously are issues as a result of this commit.

I think the original picture has an impact on the result. In Canny mode for sure.
Return preview as inputs! Please!
