yeah the site is around a month old, as for profile pics that is totally down to the user if they decide to upload one or not, some users have uploaded pics but your right the majority havent, there is no restriction on that.
in time you will see the website get busier with more meets and more members
as for the images in the gallery i will look into it but i dont think anyone else has had any problems, maybe try to resize the pictures if they are too big and make sure the format is correct.
any other problems just yell
