Hi,
I have no pic on first page on the random block. When I add pics, it sometimes works and then I have "No Image to display". In sub-categories it works fine.
Do you know why?
Sometimes the random image block shows the random images of the particular album you're in, and not the whole gallery. If that album does not have pictures, it will show no pictures in the random block.
If you want to see the random images of the whole gallery, you have to go to the start page.
