Side note: When posting code (or templates) here, enclose the code (or template) between lines of three backtick - ` characters. This means you’ll have a line of ```, then your code, then another line of ```. This forces the forum software to keep your code properly formatted. (I’ve taken the liberty of editing this post for this.)

I don’t know how you’re managing this field (or the images themselves) in your system, but this isn’t the typical way of handling them.

How are you adding images to your system?

What are you using for the src attribute in the img tag? (That’s normally where the url is supplied.)
