Attachment selection for thumbnail display

[masterchief]

I am looking to compensate a developer for an addon that will write out similar code to what is provided in code block below. I want to select attached images from message threads and place them in thumbnail gallery. Ideally it would be part of attachment approval method. Future selections would be added as shown.

<div style="background-color: #65A5D1; color: white; border: 1px solid #7192a8; padding-left: 10px; -moz-border-radius: 5px 5px 0px 0px; width: 891px; overflow: auto;">
