Publishing Tasks: Phase 6 Sustainability + Accessibility

Gallery image

Each lesson in our directory is accompanied by an image.

ProgHist can make this selection, or an author/editor can make a suggestion.

Step 1. Source an image

The image must be:

• copyright-free
• non-offensive
• an illustration (not a photograph)
• at least 200 pixels width and height

Image collections of the British Library, Internet Archive Book Images, Library of Congress Maps or the Virtual Manuscript Library of Switzerland are useful places to search

Step 2. Save two versions

• Save the image as a .png
• Duplicate the .png — (we need two versions)

Step 3. Version 1: original

• Name the original image so that it shares its name with the lesson file, adding the word “original”: lesson-file-name-here-original.png

Step 4. Version 2: gallery

Prepare the duplicate image for our gallery:

• Crop to a square (taking care not to remove any key features)
• Re-size to 200x200 pixels
• Convert to greyscale, adjust the contrast or tonal values if necessary
• Name the gallery image so that it shares exactly the same name as the lesson file: lesson-file-name-here.png

Step 5. Upload

• Upload Version 2 to the directory /gallery
• Upload Version 1 to the sub-directory /gallery/originals
