As I surf through several forums on my smartphone I use tapa regulary and appreciate it. I have the same problem you described here but in no other forum. Some posts with pictures work well and I presume those pictures were loaded onto tapa.
The tapa-admins say that it is an rwi-issue and you say it's a tapa-issue. I have a lot to do with software integration at work to know that both of you are right
...
Anyway, the mobile style of the rwi-internetsite is an alternative for smartphone users. The only thing there is the "donate now" post and the adverts, that cocer my screen completly everytime I want to read a thread or a post. For me that is annoying, though I understand you need the money to run this fantastic forum.
I don't know if admins communicate with other forum admins. The German uhrforum.de is a really good example for a mobile style. There is no difference between the smartphone and the computer version.
Means: I will accept what I see but it is not always fun.
