* Adds a button that opens the currently selected subdirectory using
the default OS file manager
* Improve output gallery handling of having images deleted out from
under it.
* Don't show VAE or LoRA lines in parameter info panel when their
value is 'None'
* Use a css class for small icon buttons on the output gallery
tab instead using the same id for multiple buttons
* On startup report that cleaning up of temp files is taking place, in
case it takes a long time.
* Have the output gallery tab delete any zero length temporary files
generated by gradio < 3.32.0 for its gallery control whenever it
needs to update that control with images. This prevents such
files multiplying out of control.
This fix the gallery component of the output gallery dumping temporary
files into the standard folders rather than shark_tmp so those files never
got cleared out on restart and would build up.
* WebUI: Adds an Output Gallery tab
Adds an new Output Gallery tab to the ui/webui with these features:
* Subdirectory select dropdown listing subdirectories at any depth below
the <output_dir>/generated_imgs directory,
* Large, full height, gallery area displaying the images in the selected
subdirectory. Shows nod logo when no images are in the selected
subdirectory.
* Slider that changes the number of columns of images that the gallery
displays from between 1 to 16 columns (defaults to 4).
* Expandable parameter info panel showing any generation parameters
saved in the file of the selected image for PNGs, alternatively the
image's EXIF data for JPEGs
* Send to buttons for txt2img, img2img, inpaint, outpaint and upscaler.
* Auto update of gallery and gallery label (to show generation status),
when a new image is generated by any of the stable diffusion tabs, and
is outputted to the currently selected subdirectory.
* Command line option for enabling and disabling the output gallery
(defaults to enabled)
* Command line option for following symlinks when getting entries
for the subdirectory list (defaults to off, as Python os.walk doesn't
check for circular references if following symlinks)
* Reformat with black
Reformat changes with black and then adjust some places where black's
formatting then needed some rephrasing of the code to make things
clearer.
* Add back transformers and sd_cancel imports
Adds back the transformers import in index.py needed for .exe
generation. Add comment so it doesn't get mistakenly removed
next time.
Adds back sd_cancel import in upscaler.py that is currently unused
but should be being used for the 'Stop' button.
