[Feature Request]: Option setting to not save a skipped image #12335

not exactly what the feature request asked, he's asking for interactive implementation....

new opt Saving images/grids > Don't save incomplete images

if enabled will skip saving to storage when the image is interrupted or skipped
default not enabled

saving of image grid is not affected it's not governed under this setting
and even if the images are not saved the result was still show up in web UI

There's another PR that I keep putting off that does something similar...

#8608

This one's a lot shorter so that's great.

opts.samples_save and not p.do_not_save_samples and not (opts.dont_save_incomplete_images and (state.interrupted or state.skipped)) should probably be made into an inline function

[w-e-w]

yeah I'll make it into a function so that it's easier to reuse and more readable
don't know why I didn't think of that

[AUTOMATIC1111]

or just calculated and put into variable

[w-e-w]

should be good this time
the function is used once for high-respass
for saving the normal pipeline it is calculated once then save to a var

[AUTOMATIC1111]

opts.save is a function that writes config to file; it is always not False.
