Stack Overflow lets you upload an image to a question or answer, but there is an important rule of thumb: never post code or errors as a screenshot — paste them as text so they are searchable and copyable. Screenshots are for things text cannot show.
When a screenshot is right
- A visual bug — a broken layout, a rendering glitch, a chart.
- A tool's UI or a settings panel.
- Anything where the appearance is the question.
Add the screenshot as a link
- Open sshot.online and paste or drop your screenshot.
- Copy the share link and add it to your post, or use the image button and paste the direct link.
Post code and errors as text
For source code, stack traces, and terminal output, paste the text — or if it is long, share a code link alongside a short inline excerpt. That keeps your question searchable while still giving the full context. Both tools are free and need no account.
