Help needed. Why are my image links broken?

I'd really appreciate any help with this.

All of my image links are broken.

I'm sure this is really basic stuff to many, but
I'm completely new to using an editor.

I could hire someone to fix this but it will just come up again and I want to learn how to do this myself.

I made a few changes to a PLR squeeze page using Kompozer and uploaded the page using File Zilla. The images are also uploaded in a file called images.

I set up the website files on my computer to mirror the website files on the server.

I checked the image properties and they all begin like this: "file:///"
so I'm pretty sure that means they are pointing to my computer and not my server. If that is the problem, here's what I have tried so far.

I've tried deleting all the files on the server and starting over.
I've tried to rename the files. Clueless as to what else to try.

I "Googled" for an answer to this problem. One tutorial said when using Kompozer to upload the page before you add any images and then go back and add the images, but I've already uploaded the page with images, infact it came with images.

I'd so appreciate any help with this.
Thanks, Maureen
