first you should check if your base64 string is valid.you can do that using any of the online tools like base64-image .how ever please refer to this EXAMPLE fiddle which displays a base64 image using html img control.

EDIT: please check in your 'IMG' src have data:image/jpeg;base64, before the base64 string.this where it determines the image format.if this doen't work please try replacing 'jpeg' with 'png' eg:- data:image/png;base64,
