Hello Brajesh and thanks so much for your help.

This morning, I can display PDF in lightbox nicely, all loads in a few seconds ! So well I am just crossing fingers this will last.

Anyway, I think this would be a nice improvment to give choice as to what can be opened in a lightbox, and what cannot.
Especially for docs, if we could choose the icon could lead directly to the doc (with or without google viewer) that would come handy. I am not a developper, so I do not realize the load of work…

Last thing, are you open to custom work ? If I cannot tackle the incompatibilities with my theme, I’d rather trust you with this work then the theme dev who does not seem to know much about buddypress…

Whatever the case, THANKS. You are a great person !

Thank you for checking Brajesh. Well, I don’t understand a thing since I have the problem, and I am not the only one (users complain too…)

Right I do not have the problem either, they do open on first click and display quite fast.

Well this is just crazy..Anyother way you know to upload and display photo in groups ? As to PDF, a link will do..

Thanks anyway

Hello Brajesh, thanks for your answer and sorry for my being so slow but I have been somewhat under the water for the last month or so.

So well I added your code, but alas it did not work as expected. if you need any informationabout my installation, please tell me so
