Images don't display

Zoho creator seems like a really robust platform but my first impressions are that it is buggy and unpolished. I hope I'm wrong but I suspect this forum post will land in a black hole somewhere. I am trying to create a simple employee directory that includes a photo for demo purposes. I have followed the instructions in Zoho's help file but the image that is supposed to appear in the help file just displays the infamous black "x" icon indicating the picture no longer exists or the link is broken. Regardless, I've done what would be intuitively obvious and I can get the file explorer window to pop up when I click on the upload image icon, but when I select the picture I want to upload, nothing happens; no error message or anything. Any help would be appreciated. I have looked at Knack and Caspio in comparison. Knack works very well but it is simply not robust enough for my needs.
