Inserting external HTML/CGI in WordPress Page

When you you want to make a WP page – you mean a Page, like described here:
https://codex.www.ads-software.com/Pages ?
If yes, think it this way: maybe it is better to create a Page template with all the code you want in it and then create a new Page using that template.

On wordpress 1.5, I had linked to my flickr photo feed, and now after upgrading to 2.0, I’m finding that the feed no longer works. I had originally inserted the html code supplied by flickr and it worked fine until the upgrade. It seems that in 2.0, a major change has been made in how images are linked as the <img src> method I had always used doesnt work any more and I had to use the ‘blog this’ feature on flickr. Is it possible for me to re-enable this photo feed?

this is all that appears on the page now:
https://www.interactive-bot.com/wordpress/?page_id=20

code used:
<!– Start of Flickr Badge –> <style> .zg_div {margin:0px 5px 5px 0px; width:117px;} .zg_div_inner { color:#666666; text-align:center; font-family:arial, helvetica; font-size:11px;} .zg_div a, .zg_div a:hover, .zg_div a:visited {color:#3993ff; background:inherit !important; text-decoration:none !important;}</style><script type=”text/javascript”> zg_insert_badge = function() { var zg_bg_color = ‘ffffff’; var zgi_url = ‘https://www.flickr.com/apps/badge/badge_iframe.gne?zg_bg_color=’+zg_bg_color+’&amp;amp;amp;zg_person_id=59372405%40N00&#8217;; document.write(‘<iframe style=”background-color:#’+zg_bg_color+’; border-color:#’+zg_bg_color+’; border:none;” width=”113″ height=”151″ frameborder=”0″ scrolling=”no” src=”‘+zgi_url+'” mce_src=”‘+zgi_url+'” title=”Flickr Badge”></iframe>’); if (document.getElementById) document.write(‘

Thank you Moshu. I will try that and see if it works. Yes, I am referring to a “Page” created in the WordPress program.
