Omeka Zoom Plugin
This is a plugin for the Omeka web publishing platform to enable jpg images to be turned into interactive zoom-able widget. It enables any jpg attached to an item to be converted into tiles and replaces the thumbnail normally presented with a javascript zoom tool. Check out the demo and details below.

The plugin is a combination of many resources:
- Openlayers.org viewer http://openlayers.org/
- Zoomify tile format http://www.zoomify.com/
- Adam Smith 's PHP tile cutter http://zoomifyimage.sourceforge.net/
- Zoomify for Openlayers project: http://plone.itc.nl/OpenLayers/examples/zoomify.html
Some Notes:
- To Use: a new tab is added when you edit an item (see screen shot). You can enable zooming by clicking its check box and saving. You can unzoom by clicking the un-zoom all checkbox and saving.
- To change the look and size of the zoom widiget edit: OpenLayerZoom/views/shared/common/theme/default/style.css
- The zoom tiles are stored in archive/zoom_tiles/ this directory will be removed if you uninstall the plugin
- Zooming an image will double the space (at least) that it takes up on the server
- I haven't tested huge images, it works fine for image I've teseted, up to 20megs
- Only works for jpg files
- Targeted at the 1.4+ versions of omeka but might work for earlier verions, haven't tested
