Re: How to display avatars in normal theme at 125px?
@ John James Jacoby,
I had a look in the bp-events-avatar.php to understand more what’s going on there.
I’m thinking the avatar part could be like it is now.
It would be enough, if the original resized image would be available.
I did some changes to the bp-events-avatar.php and make a plugin from it.
For the moment, I will use the modified functions in custom components until you offer a better way to do it. I think it would be really great if the original resized image would be saved by the core.
Be careful!
This Plugin is just a play around on a fun buddypress installation.
