Thanks for the reply. I tried different options, including the link You specified. Only works the code that I presented above and it displays all the field group 739. I need to withdraw one field cover_profile, which is also located in the group of 739, but it does not want displayed)
The last thing I tried:
<?php if( get_field('cover_profile') ): ?>
<img src="<?php the_field('cover_profile'); ?>" />
<?php endif; ?>
Not working. In the place where there should be picture – empty.
