I've built a few sites now using Silverstripe and I seem to have an issue with the Gallery module in each of the sites. Sometimes when the image starts to load up, the screen dims and the box starts to draw. But then, as the box is still at or near its minimum it stops. That's it. Nothing remains but a little box on the screen where a much larger box with my image is supposed to be.
Its intermittent for me (about 1 in 10 clicks) but my designer is reporting an almost constant error rate. It seems to happen on Mac or Windows. In several browsers that we've tried.
Here is a screenshot my designer sent to me...
