o8_pics_size

Run the app to open a file picker limited to Excel files (.xls, .xlsx). After selecting a file, it reads the workbook sheet names and opens a terminal picker where you choose a sheet with arrow keys and Enter. Then it reads the header row and asks you to map three columns using the same TUI picker:

• Cikkszám
• Url
• img_sequence

After mapping, it downloads each image from the selected Url column, reads image metadata, and writes a new Excel file next to the source workbook as result_[uuid].xlsx. For testing, it currently processes only the first 100 non-empty URL rows.

Output columns:

• Cikkszám
• Sqeuence
• Url
• Width
• Height
• Size (KB)
