For adding image field, you can try using plugin and always try to avoid overwrite whole class.

</config>
Vendor/Module/Plugin/Block/Adminhtml/User/Edit/Tab/Main.php
namespace Vendor\Module\Plugin\Block\Adminhtml\User\Edit\Tab;
class Main
{
/**

public function aroundGetFormHtml(
\Magento\User\Block\User\Edit\Tab\Main $subject,
\Closure $proceed
)
{
$form = $subject->getForm();
if (is_object($form)) {
$fieldset = $form->addFieldset('admin_user_image', ['legend' => __('User Image')]);
$fieldset->addField(
'user_image',
'image',
[

'label' => __('Image'),

'title' => __('Image'),
'required' => false,
'note' => 'Allow image type: jpg, jpeg, png'
]
);
$subject->setForm($form);
}
return $proceed();
}
}
