Thailand e-Visa: “We detected that your photograph might fail to meet the guidelines.”

What the warning means

The portal sends your portrait to an automatic check against the ICAO photo standard. When the check passes it says “The photograph quality meets the ICAO standard”; when it doesn’t, you see this warning and a list of suggestions. It is a warning about your photo, not a technical upload error, so the fix is almost always a retake.

What each suggestion means

Suggestion shown	What to change
“Head should take up 70-80% of photo. Centered and looking forward.”	Your head is too small, off-centre or turned. In the portal’s code this one is shown for a head-angle failure, so first make sure you face the camera straight on.
“Expression should be neutral and with your mouth closed”	Close your mouth, no smile.
“Background should be plain. No spots, lines or curves visible in the photo.”	Use a plain wall with nothing behind you.
“Background should be light-coloured.”	Use a white or very light wall.
“Face should have appropriate brightness and good contrast between face, hair and background.”	Face a window; the face shouldn’t be dark against a bright background.
“Face should be centered and in-alignment from crown to chin and from the left ear to the right ear.”	Keep your head level and straight, in the middle of the photo.
“Left eye should be visible…” / “Right eye should be visible…”	Open both eyes; remove tinted glasses; move hair and avoid glare on glasses.
“Photo should be free from reflection or glare.”	No flash; tilt glasses or take them off.
“Skin tone should be natural.”	No filters or beauty mode; use daylight.
“There must be no other people or object in the photo.”	Only you in the frame.

How to fix it

1. Stand about 1 m (3 ft) in front of a plain, light wall and face a window; flash off.
2. Ask someone to take the photo at your eye level, framing your head and shoulders with your head in the middle.
3. Look straight at the camera with a neutral expression and your mouth closed.
4. Upload the original photo as a JPG under 3 MB, without filters or edits.
