Two input boxes near each other on ACP (Additonal fields)

[Sun Zaza]

Hello,

I have a question:

When I add for example two additonal fields using (db_field_definitions.php), it shown on the ACP under each other.
I want them on one line (Near each other)

More explanation:
db_field_definitions.php
$additional_image_fields['image_city'] = array($lang['image_city'], "text", 0);
$additional_image_fields['image_country'] = array($lang['country'], "text", 0);

ACP

Image city

Image country

I don't want them like this. I prefer the two input boxes near each other. Otherwize I will get e very long page.
Is that possible? (Everything is possible with PHP!!!)

Thank you in advance for any help
