Why is my image with URL that links to external site in a custom block not showing? I made a custom block in header that houses the following html along with 4 more of the same html for different social media sites:

a href="https://socialmediasite.com" target="_blank" 
img src="/images/socialmedialink1_icon_32x32.png" alt="Social Media link" style="width: 32px; height: 32px; border:0" 
/a

The problems aren't the links because they do work. The problem is the images aren't showing up and only showing up as broken links so there's a problem with the img src link. I made a folder under root directory named images using my website hosting companies file manager and the images have been uploaded to that folder so I don't know what I'm missing. Am I missing something in the img src or something else before the a href or can it just not be done using only a custom block?
Try using the full site url for the src tags.

Prepend return value of $base_url and the rest of your path leading up to the image to your src attribute
