Thread:Help talk:Gallery format/Overlay images not available for displaying/reply (9)

I'm getting the same error, though I'm using English language. MW 1.19.3, SMW 1.8.0.3, SRF 1.8 on IIS7.5 Windows Server 2008 R2.

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.
