Insert Image in PDF iPhone (tutorial)

Why It Doesn't Work

• The thumbnail text 'INSERT IMAGE' just repeats the video title, adding no new information.
• The PDF icon is too small and lacks contrast, making it hard to see.
• The dark background and dark phone blend together, reducing visual impact.
• The overall composition is static and lacks any sense of action or intrigue.
• The thumbnail fails to visually demonstrate the 'how-to' aspect of the tutorial.
