Module Random Image

Not able to have Module Random Image working. It shows the image filename OK in any position, but no image. I have tried different sizes and resolutions with same results. Gallery and Carousel are working OK though. What I might be doing wrong?

That is core joomla module, so probably it's ok, check image links if there are good, when you go to view source than click on img src link to see what you get. You may get not found - then link is bad , of forbidden - your images dont have read permission (CHMOD).

Thanks so much. Indeed it was something related with a bad link. Thanks for your prompt answer.
