Once text is hidden in an image the saved picture is still a 'picture', it will load just like any other image and appear as it did before. Compression errors provide a hiding place for data, but high compression reduces the amount of data available to hold the payload, raising the encoding density, which facilitates easier detection (in extreme cases, even by casual observation).
