答

That's the data url displayed as text, the browser doesn't know its a jpeg.
Add the correct mime type to the url and it should work

echo 'data:image/jpeg;base64,'.$row_img['image'];

答

Your content type for your data is wrong. image is not valid. It should be image/png or image/jpeg or something similar depending on the type of image.

From what you posted, it looks like your image is a JPEG.

答

Because the browser has no way to know the mime type with inline image. Open them with img tag is Ok because you tell the browser it's an image. But without context in a new tab it s just a random string

EDIT : use a full correct mime

<img src="data:image/gif;base64,R0lGODlhEAAOALMAAOazToeHh0tLS/7LZv/0jvb29t/f3//Ub//ge8WSLf/rhf/3kdbW1mxsbP//mf///yH5BAAAAAAALAAAAAAQAA4AAARe8L1Ekyky67QZ1hLnjM5UUde0ECwLJoExKcppV0aCcGCmTIHEIUEqjgaORCMxIC6e0CcguWw6aFjsVMkkIr7g77ZKPJjPZqIyd7sJAgVGoEGv2xsBxqNgYPj/gAwXEQA7" alt"" />
