Author: Pierre Lescanne (own work, self-published)
Credit line (for figcaption): John Backus, 1989. Photo by Pierre Lescanne, via Wikimedia Commons (CC BY-SA 4.0).
Dimensions: 238 x 356 px
Notes: Only free-licensed Backus portrait on Wikimedia Commons. Small resolution (works at figure size, not full-width). Taken in 1989, twelve years after his Turing Award. No public-domain IBM-era portrait exists on a free platform.

Existing file, not overwritten. Source/credit line should be carried over from earlier use.
Alternate console photo downloaded as IBM_704_console.jpg (see below).

Dimensions: 2420 x 1943 px
Notes: Excellent primary-source photo showing the 704 console being operated. Sharp, high-resolution, clearly identifies operators. Perfect for the “operator at console” slot.

Dimensions: 985 x 1255 px
Notes: Clean solo portrait, good resolution. The standard NASA image used across publications.

Dimensions: 1896 x 1502 px
Notes: The single best group photo of the West Area Computers, featuring Vaughan with her team. High resolution, suitable for large figure.

Credit line (for figcaption): Cover of “The Fortran Automatic Coding System for the IBM 704 EDPM,” IBM, 15 October 1956 — the first Fortran programmer’s reference manual. Public domain.
Dimensions: 610 x 780 px
Notes: Modest resolution but definitive primary-source cover. The most-reproduced Fortran manual image in computing history.

Derived from: IBM_704_console.jpg (ARC-1958-A-24321, NASA Ames, public domain)
Processing: Resized to 1600 wide, center-cropped to 1600x900 (standard blog header aspect)

Credit line (for figcaption): IBM 704 operators William Mersman and Marcie Smith at NASA Ames, 1958. Photo: NASA, public domain.
Dimensions: 1600 x 900 px
Notes: Cropped from the same high-res ARC-1958 plate. Dramatic wide composition showing the full 704 console and both operators. Matches existing header aspect ratios in the repo.

7 usable images in place (6 newly downloaded + existing IBM_704_NACA.jpg retained):

Notes on coverage:

Backus portrait: CC BY-SA 4.0, 1989, is the best free-licensed Backus image anywhere. IBM Archives photos are copyrighted. No NASA/government portrait exists (Backus was private-sector at IBM).
No standalone IBM 7090/7094 image added — IBM_704_console.jpg covers the operating-console slot, and IBM_704_NACA.jpg remains for an “at NACA” shot.
No punch-card deck photo added — the coding form and manual cover together carry the “Fortran artifact” theme; a card deck would be redundant. Can be added later from File:Iannis_Xenakis_Fortran_Program.jpg if desired.
