Design and cache

Open System > Plugins > Content - Image Tooltip > Design.

Look

• Tooltip background, text colour, and accent colour
• Max width (default tip width in pixels)
• Corner radius
• Tooltip image fit: Contain (default) shows the full image. Cover fills the panel and may crop edges. Optional on one tip with fit="cover" or fit="contain".

Media cache

• Cache resized images: Yes (default) writes files under images/cache/image-tooltip. No uses the original URLs.
• WebP thumbnails: shown when cache is Yes. Local images are resized; remote https URLs are left unchanged.
• WebP quality: 40 to 100
• Clear image cache: deletes generated files
• Remove broken files: deletes empty or tiny cache files left by older versions

Thumbs with thumbwidth use a square box and never grow past the column width, so a row of icons stays even.
