Output - a CSV named "ocrText-[Date-time].csv", containing these columns: ## Output
- "image" = filename for each JPG and JPEG A CSV named "ocrText-[Date-time].csv", containing these columns:
- "line_count" = number of lines in each OCR transcription - **"image"** = filename for each JPG and JPEG
- "Line1" - "Line[N]" = text for each line in the OCR transcription. - **"line_count"** = number of lines in each OCR transcription
- the number of "Line" columns will match the maximum number of lines as needed. - **"Line1"** - "Line[N]" = text for each line in the OCR transcription.
