[xwiki-users] User directory avatar image resize problem

Hey All, I installed the Xwiki 5.1 Enterprise edition. When a user updates his profile picture it is re sized automatically in all the pages(e.g. profile page, the thumbnail shown in Add Comments section etc.). But when I view in the user directory the automatic re size does not happen. The image is shown in a huge size(it does not get re sized). Could anyone please help with this issue. Thanks and Regards Sunil
