Optimize Tkinter Game Browser

I have a small Tkinter-based game browser that pulls data from the Nintendo titledb JSON feed. Right now two things are holding it back: the interface becomes sluggish once the search results appear, and the cover art that should come from each bannerUrl never renders on screen. What I need within the next few hours is a clean refactor that tackles both issues together. The script should feel snappy while a user types or scrolls, and every result must reliably display its JPEG cover pulled directly from the URL contained in the JSON (example: [login to view URL]). You are free to adjust the image-loading mechanism—threading, asyncio, Pillow, caching, or swapping out my current “other” method for the Requests library—so long as it remains a pure-Python solution that runs on the standard CPython interpreter with Tkinter. The finished file(s) should launch without lag, display every cover in the result list, and keep the code readable for future tweaks. Deliverable: the updated Python script (plus any helper modules you introduce) that I can drop in and run. I will test by searching several titles; acceptance is a smooth GUI with all covers visible and no noticeable stutter. my budget is 25 usd for the one fix
