# AutoDraw Guide photos

These photos are instructional references. They are not AutoDraw output, customer
project records, CorelDRAW acceptance, cutting acceptance, or physical assembly
acceptance. All three web assets were acquired on 2026-09-15, center-cropped and
resized to 1200 × 800 pixels, and encoded as WebP for the Guide.

## Generation fallback record

The preferred synthetic-photo prompts were attempted with the built-in OpenAI
ImageGen tool on 2026-09-15. The call returned a temporary usage-limit error before
any image was generated. These documented Wikimedia Commons photos were used so
the Guide could ship with real, traceable instructional imagery.
