Choose suitable image sizes
Choose source images for the space they occupy, then verify the actual crop and loading behavior.
Select a screenshot to enlarge it.
Steps
- Identify whether the image is a background, logo, question reference, or answer choice.
Question media is separate from theme backgrounds and visual answer choices. - Use a sharp source with sensible file size. Keep important details away from edges that may be cropped on narrow screens.
Question media illustrates the question. Image answer choices are configured separately. - Add it through the appropriate media or theme control and inspect the offered crop or layout options.
Long labels wrap on a narrow screen. Shorten labels or split the task when the grid becomes difficult to read. - Preview desktop and mobile, including a slower connection and browser zoom where practical.
Check before you rely on it
There is no single ideal pixel size for every placement. A logo and a full-screen background need different proportions.
If you need help
Do not enlarge a tiny image and expect lost detail to return. Replace it with a better source and keep key instructions as text.
Contact support with the relevant screen, time, and a redacted description. Keep credentials and private respondent information out of screenshots.
