The use of images in the teaching of sciences is quite a routine. Research has been showing the necessity of teaching the reading of images since their reading is not straightforward. As with any other resource, the teacher has an indispensable role, direct or indirect, in the way images work in the classroom context. Beyond of those presuppositions, it was considered that the reading of images depends on the historically-built conditions. The subject is part of those conditions. So, it is fundamental that we think about the role of teacher education courses in the understanding of the manner of mediation of the use of images when teaching science. In this work we analyzed in what aspects a short duration course of in-service teacher education influenced teachers' relationship with the images, their representations and possible actions in classroom. At the end of the course it was realised that there were changes in the ways teachers thought about images and in their relationship with images within science teaching and learning processes.
