A lot of writer's block happens because we don't feel immersed in new or interesting topics, bordering on monotony. Then we miss the opportunity to publish on something fresh.

Remember that it is essential to cite well the sources of the images. They should point exactly to the image hosted on a specific site, where the author of the image can be seen. It is not correct to direct to a set of images, because we do not know its author or if it is royalty free or a paid image.
