[Bug]: Disabling "Always save all generated images" causes FileNotFoundError

[ChristophHaag]

Is there an existing issue for this?

• [X] I have searched the existing issues and checked the recent builds/commits

What happened?

On archlinux I ran ./webui.sh from the git repo, disabled "Always save all generated images" and ran into this error.

Steps to reproduce the problem

1. Disable settings -> Saving images/grids -> Always save all generated images, click apply settings.
2. Go to txt2image and generate something
3. Get FileNotFoundError error and no image in the webui

What should have happened?

the webui should display the generated image, just not autosave it.

on linux it's trying to save the grid file into /tmp/gradio. i have found 2 workarounds: 1) create the directory /tmp/gradio. it has the drawback of getting deleted after a reboot, so i have to recreate it. 2) select a different directory in settings -> saving image/grids (1st choice) -> directory for temporary images (almost last choice). it has the drawback of not deleting the files after a reboot - so you need to clean them manually
