+ нужно было в моем base64 удалить "\" и все заработало, может кому то поможет)

 

[Yuriy Zymlex]

мой формат base64 с помощью этого кода не декодирует...

Очень похоже, что вы его неправильно скопировали из браузера.

 

[Scorpic]

А как файл картинки, а лучше url с картинкой (чтобы не сохранять) закодировать в base64?
