Retrieve High-Res Versions of Images

I will send you an Excel workbook that contains hundreds of embedded reference images. Most of them are only thumbnails, so I need you to hunt down the exact same visuals on the web, download the best-looking copy you can locate, and save each one as a high-quality JPEG.

Target quality: about 4K (≈3840 × 2160) or higher if the original is available in an even larger size. Please keep the original file names exactly as they appear in the spreadsheet so I can drop the results straight back into my workflow without renaming.

Use whatever tools you prefer—Google Images, Bing Visual Search, TinEye, stock-photo libraries, brand archives, etc.—as long as the final JPEGs are crisp, clean, and free from watermarks.

Deliverable: a single zipped folder containing all recovered images in JPEG format, each at 4K resolution or better and bearing the same names as in the Excel file.

I’ll provide the spreadsheet as soon as we start; let me know roughly how long you think the search and download process will take once you see the scope.
