@Duddlebug,

you can change the size of the fields using css if you have worked with css. you want to add this to your child theme so you don’t lose the changes when you update your theme or image store.

If you need help with the css rules please provide a link to your site.

add this code in your child theme or into a plugin, and change the wording “To view your images please enter your login information below”. You canl also change the html if you know how.

function theme_change_imstore_login_user_form( $form, $gallery ){
$gallery_label = "ims-galbox-{$gallery->ID}";
$password_label = "ims-pwdbox-{$gallery->ID}";
$nonce = wp_create_nonce( 'ims_access_form' );
$output = '<form action="' . get_permalink( $gallery->ID ) . '" method="post">
<p class="message login">' . __( "To view your images please enter your login information below:", 'ims' ) . '</p>
<div class="ims-fields">
<label for="' . $gallery_label . '">' . __("Gallery ID:", 'ims') . '</label> 
<input type="text" id="' . $gallery_label . '" name="' . $gallery_label . '" /><span class="linebreak"></span>
<label for="' . $password_label . '">' . __("Password:", 'ims') . '
</label> <input name="' . $password_label . '" id="' . $password_label . '" type="password" />
<span class="linebreak"></span>
<input type="submit" name="login-imstore" value="' . esc_attr__("log in", 'ims') . '" />
<input type="hidden" name="_wpnonce" value="' . esc_attr( $nonce ) . '" />
' . apply_filters( 'ims_after_login_form', '' ) . '
</div>
</form>
';
return $output;
}
add_filter( 'ims_login_form', 'theme_change_imstore_login_user_form', 50, 2 );

@Duddlebug,

To hide the message use .message.login{ display:none} this will hide the message and you can add your own directly in the page.

Not sure what other display changes you need but a screenshot of what you want will help.
