You may be able to do a "lite" version of what you want. My idea is that you could use jQuery Tabs, with one tab for each project. On the tab you can have thumbnail images and the text you need. If you want the full-size images to be shown in light box style, you can add

include ColorBox="true"

to the <portal:ScriptLoader declaration in the Layout.Master for your skin. Then on each thumbnail image, include the "cblink" class like this:

<a class="cblink" href=...

That said though, I believe the only way to really do this right would be to create a custom feature.

Hope that helps,

No you should not try to use an existing content feature inside another custom content feature. You can borrow code from the image gallery if you find code that is useful to you.
