Theme Functions php file broken

I am having a bit of a problem. I was putting in some images on my website, https://test.eucantina.net, and I stuck an image file in my Functions.php file. This caused my site to go blank and display the message-

“Parse error: syntax error, unexpected ‘<‘ in /home3/asiolcom/public_html/eucantina_test/wp-content/themes/christmas-is-near/functions.php on line 50”

The problem is, I cant get into my dashboard either, because it displays the exact same message, so I cant fix the problem.

Can anyone help me with this?
