Finished resourcing all the image files

Started the process of resourcing all the images to use the Steam Cloud instead of linking to other sites. This is the courteous thing to do to not eat up the bandwidth of these other sites. This has the added benefit of future-proofing the mod in case the other sites shut down/ change the urls of the images.

This update also fixes the sprite of Paras to use its non-shiny sprite.

Initial Upload. All 151 gen 1 pokemon with all their main series forms (gender differences, mega forms, gmax forms, alola forms, galar forms, and ash cap pikachus)
