Overlay images not available for displaying

From semantic-mediawiki.org

I'm getting the same error, though I'm using English language. MW 1.19.3, SMW, SRF 1.8 on IIS7.5 Windows Server 2008 R2.

 {{#ask: [[Category:some category]] [[Has some property::property1]]

The little square boxes don't show up. And when I hover over the image, the browser shows the destination URL to be the page URL, whereas on the demo page, it shows the destination URL as the image's File: URL or the actual image URL.

I wonder if this has something to do with a conflict with another extension.

Without the overlay=yes parameter, a standard gallery is shown, and inspecting the destination URL when hovered over the image shows the File: URL.

With no accessible public source available to inspect the issue and the format working on smw.org, there is yet little chance for making suggestions about the possible cause or solution.

The only advice I can give is to compare the examples on smw.org with the examples you have employed and check for possible JavaScript errors (see here).

PS: The change cited above for multilingual namespace support is only deployed with SMW/SRF 1.9.

I know this is old, but I just ran across this problem myself. On Windows servers, the href uses "%3A" instead of ":". Changing

var title = image.attr( 'href' ).split( encodedNsText + ':' ), to var title = image.attr( 'href' ).split( encodedNsText + '%3A' ),

on line 96 of ext.srf.gallery.overlay.js worked for me.
