Best Resolution for Blog Use
Blog Post Types That Use Thumbnails
📋 Video Roundups
"Top 10 cooking tutorials" or "Best tech reviews this month" — each entry needs its thumbnail for visual appeal and scanability.
📝 Product Reviews
Referencing a video review? Include its thumbnail for visual context. Readers instantly recognize the video they may have watched.
📊 Channel Analysis
Writing about a creator's strategy? Download thumbnails to illustrate your analysis points with real examples.
🎓 Educational Content
Tutorial posts referencing video content benefit from thumbnail previews that give readers a visual preview before clicking through.
Attribution Best Practices
Standard Attribution Format
Use: "Thumbnail from '[Video Title]' by [Channel Name]" and link the image or caption to the original video URL.
Fair Use Contexts
Commentary, criticism, review, education, and news reporting generally fall under fair use. Always add your own analysis alongside the image.
When to Seek Permission
If using thumbnails in commercial contexts (paid ads, merchandise) or purely decoratively without commentary, contact the creator first.
Common Issues (and Fixes)
Issue: "Thumbnail loads slowly on my blog"
Fix: Use 480×360 resolution instead of max. Add lazy loading (loading="lazy") to img tags. Compress with TinyPNG before uploading.
Issue: "Thumbnail looks blurry on my blog"
Fix: You are likely displaying a low-res version at a large size. Download at 1280×720 for images displayed wider than 500px.
