the XOOPS core does not have this feature
but the yogurt module have a feature where you can
upload as many picture allowed...the picture is resize automatically by imagemagick and then you can set any of the uploaded picture as avatar
btw trabis is working on a picture gallery based on yogurt where you can do exactly the same thing..
still not working properly though
http://www.xuups.com/modules/publisher/item.php?itemid=23avatar auto resize should be in core...not all of user is tech savy...many don;t know how to resize their pics
BUT if you mean just resize it when display as example in user info just change the user info template and change the width and height of avatar to 50 , 50
