Where do I place my ad info on this wp theme sidebar.php

This is located in the sidebar.php file for predetermined adspace. I've tried putting the image URL and the link URL in separetely and by generated code, but I get an error every time. This is the code:

<div class="box"> <!-- Replace to your affiliate link -->
    <a href="#"><img src="<?php bloginfo('stylesheet_directory');?>/images/ads125125.jpg" border="0px"></a>
    <a href="#"><img src="<?php bloginfo('stylesheet_directory');?>/images/ads125125.jpg" border="0px"></a>
    <a href="#" target="_blank"><img src="<?php bloginfo('stylesheet_directory');?>/images/ads125125.jpg" border="0px"></a>
    <a href="#"><i开发者_JAVA技巧mg src="<?php bloginfo('stylesheet_directory');?>/images/ads125125.jpg" border="0px"></a>
    <a href="#"><img src="<?php bloginfo('stylesheet_directory');?>/images/ads125125.jpg" border="0px"></a>
    <a href="#" target="_blank"><img src="<?php bloginfo('stylesheet_directory');?>/images/ads125125.jpg" border="0px"></a>
</div>

I also do not see codes for placement in the sidebar such as left, center....or any other placement parameters. The errors vary. unexpected ">" line 6, unexpected "?" line 8, always an unexpected "something" line something. Always introd as syntax error. – Archangelm 2 hours ago Any help would be a blessing!!!

Check your stylesheet directory. Place your images in the images folder and replace the image name like use your image name instead of ads125125.jpg. To put your ads links change # with your ads links from
