Not all classified ads include photos; it is up to each user whether to upload photos or other images with their ads.
If you are not seeing any photos, then the most likely cause is interference with ad-blocking software on your computer. There is nothing we can do about this. The best we can suggest is to exclude e-beira.com/classifieds in your ad-blocker settings. (E-Beira does not use any third-party ad systems, so you are quite safe doing that.)
