Based on the code by Vulpes101 somewhere else in the comments, i fixed it up so it should work and download all the images to the right palace.
Put the code from the pastebin in a .ps1 file in the same directory as the "waifu_solitarire.exe". you can then run the ps1 file and it should take all the images from gelbooru for the tag you enter.
The code is all commented so feel free to check through it first and modify it where needed, if there is an issue with the code and you fix it please reply here.

Currently the way the code works that would not be possible without rewriting the tag searching part. To make it so you could, you would likely want it to loop thought the tag selection code until a keyword ("done" for example) would let it pass from there you would need some code to generate the link. From there the second half of the code should be the same. I would currently not be able to make these changes but if you or anyone else wants to feel free.
