Sorry to hear that you're having problems with photo's. Photo's should be common jpg's files not links. If you're trying with a smartphone, try with a different device like a PC, Laptop or Tablet. Another suggestion would be to try the process using a different browser.
If all that fails, you can send the Admin Tech Team a message using the "Contact Us" Link at the Bottom of every Classified or Forum Page:
