I'm assuming that nothing has really changed on either of these 2 computers that you know of, and it just recently started doing it to both...
1) Are pictures in the DRN Photo Gallery the only images that do not display? When you click "Photos" in the DRN menu header, do you see the recent pictures of texkxkdx? I do know that there are broken links to some of the older photos in the DRN gallery.
2) Seems odd that this behavior suddenly started happening on both computers at the same time. :think: Are both computers networked to a cable modem router? If so, shut down both computers, unplug the network cables, and unplug the power cord to the cable modem. Wait 30 seconds. Plug all network cables back in, then plug in the power cord to the cable modem, and finally boot up one of the computers. See what happens.
3) Go into Internet Options (Tools | Internet Options menu in IE), and click on the Delete Files... button, and check the Offline Content option.
4) Also under Internet Options, like MW suggested, make sure that under the Advanced tab, the Show Pictures checkbox is checked. If all else fails, can you at least right-click on a red-x image placeholder and select "Show Picture"?
5) Maybe your dad turned on CyberSitter while he is gone, and you really shouldn't be looking at those sites anyway!
Hope this helps...
