Pass The Values Of The Images Across To The Page Via Post?

I have code at present which allows me to select images on a webpage.

<img name="img5">
<img name="img4">
<img name="img3">
<script>

[Code].....

I have a simple HTML form which has checkboxes next to images. What I want to do is select one or more images press submit and on the next screen show the images which had checkboxes selected.

I can pass the values of the images across to the page via post but how would I declare the id into img name as the above example is hard coded?
