Upload your image, add a shortcode and you are done!

With our Omeka plugin, you can make your images zoomable by using the following shortcode:
Single/Multipage page viewer:
[zoomable id=46]

Example:

You can also adjust the width and the height of the viewer:
[zoomable id=46 width=336 height=280]

The id is the item id which is shown when you open an item in the Items tab.

Large images support

Large images can take a while to load on the browser. To improve the loading time, they need to be converted into tiles (think Google Maps but for your images). Included with the plugin, we have a desktop tool (Windows and macOS) that creates the tiles, and have them in one zip file for easy upload back to your Omeka Classic site. Our plugin will take care the rest.
Supported image format: JPG, TIF, ZIF (Zoomify Image Format)

Requirements

  • An Omeka Classic site that allows you to install a custom plugin. In other words, this plugin does not work on omeka.net and Omeka S.
  • Make sure PHP Zip Extension is installed on the hosting servers. Many web hosting providers such as HostGator and Siteground have it installed already.
    If you have Omeka Classic installed already, login to Admin panel, then go to System Information (bottom right corner, beside the version number) to see if the extension is installed on your site. Under PHP Extensions, find the extension that says zip, as shown in the screenshot. If you see it, that means you have the extension.
