Is my wifi router blocking images from Facebook?

I recently replaced a couple of old LinkSys WRT54G routers running DD-WRT in my home with a couple of couple of D-Link DIR-615 routers that I got as refurbs from woot.com. I bought these because the old machines only did 802.11 B/G whereas nearly everyone in the house now has a device that has 802.11 N capability.
All seems well to me, but my wife and younger daughter consistently complain that they now frequently are unable to display some images from Facebook, and that this began to occur precisely at the time that I put these new routers in.

Also, for full disclosure, I've also installed the appropriate version of DD-WRT on the new boxes, and they are set up in bridged client mode so that I can maintain a single wifi network with multiple access points in the house. The "client" machine is used primarily as a source of hardwire ethernet service to a Roku box and a DVD player near our TV.
Through some back and forth Q and A, I've determined that this is the only deficiency that either one has noted with these new routers. I've asked if they've had any other sorts of problems with Facebook, and they say that they haven't. I've asked if they have any other similar problems with other sites, and they say that they haven't. Additionally, it is not simply all images that are not showing up from Facebook, but generally it is images that have been posted to other user's picture galleries and presented as items in the main timeline. And it isn't even every one of those, just some and just sometimes. Very intermittent in my experience. The only consistent theme seems to be that this only happens on Facebook.
My wife is insistent, due to the circumstantial evidence of the timing, that the issue is with the router. She even states that she has the same problem on her Android phone when connected to our home wifi network, but never has the problem when pulling data in from her cellular data connection, or running wifi anywhere else.
Does this make sense to anyone? I think I know enough about how the web works, both from the browser side and from the network side, to say with fair confidence that it is very unlikely that this kind of problem is due to the wifi router. I have WPA security running, and everyone in the house has the correct password. Other than that, access is pretty much unrestricted. I don't have any QOS stuff running, or port mapping, etc. Pretty much generic access.
Also, I've looked at the URLs to the images that are not showing up, and see that they seem to be PHP calls rather than raw URLs, which makes sense given the complexity of Facebook. I just don't see anything that would lead me to suspect my routers are the problem. Just about everything else we need and do through them to the web works. That includes basic web use as well as a lot of video and music streaming.
Can anyone suggest what might be the issue here, particularly if I am actually missing something related to the router? I'm OK being wrong, I just want to understand where I went wrong on this.
