I've tried both solutions and it's not working here
1) decode is giving me following error.
27.0.0.1.2014-12-02.13-01-39.af379677-6327-4f4c-bc93-5ed1e5e02ed8
<class 'binascii.Error'> Incorrect padding
2) Second option is not working.
I've printed image path but it didn't display on login page.
<img
src="data:image/gif;base64,/default/show_logo/company.logo.91f2753b1fabaab6.736571756f69615f6361706974616c5f6c6f676f2e676966.gif"
