Image Publishing Guides
Practical, original guidance for preparing images before they go live. These guides support the checker with deeper context around performance, accessibility, privacy and SEO.
Recommended starting points
Use these guides to build the basic workflow: review the destination, choose dimensions, prepare image SEO and control performance before files enter a CMS.
Guides by category
Each category groups a distinct search intent and points to the tools that support the workflow.
Image SEO
Review filenames, alt text, preview context and page fit so images support the page instead of looking like isolated assets.
Image compression & formats
Choose dimensions, compression and format together. A WebP, JPG or PNG decision only works when it matches the image content and destination.
Social media image sizes
Prepare square, portrait, vertical and wide crops for link cards, feeds, thumbnails and social publishing workflows.
Metadata & privacy
Check visible details, EXIF signals and clean publishing copies before photos or screenshots become public.
Accessibility & alt text
Plan alt text around the image purpose. Useful images need context; decorative images need a quieter treatment.
Open Graph & thumbnails
Create dedicated preview images with safe areas, readable text and dimensions that match how cards are rendered.

How to use these guides
Start with the publishing goal: reduce file size, choose a format, improve accessibility, protect privacy, prepare a social preview, or make website images faster. Each guide connects the editorial decision to a practical PublishPixel tool.
What to review before publishing an image
Before uploading an image to a website, CMS, store or social platform, review five basics: dimensions, file size, format, filename and context. A technically valid image can still be too heavy, too small, unclear, poorly cropped or mismatched for the channel where it will appear.
