Thank you for using aiimages! <3
Aiimages uses a history file that is saved to "C:\Users\[Your Username]\AppData\LocalLow\sunija\aiimages" to find previous images. Did that one get deleted by any chance?
Also make sure that the outputs folder is called "outputs" and is in the same folder as the executable.
If neither of those work, you can drop the images in the application or click on the empty input image, to load them as inputs. Also you can drop the images in https://www.metadata2go.com/ to get your settings, prompt, seed, etc, to recreate the images (which is tedious, though :/).

History file and outputs folders are where they are supposed to be and the files names are unchanged. Program continues to work fine. For whatever reason I cannot drag and drop images into the application like you mentioned, but I was able to recreate the images by clicking the empty input image and loading them as input image and running them with the influence cranked all the way up.
Your reply was a big help, thanks!
