1. the filesize does not work.
2. if I force cropping the image, then it creates a second smaller image in the folder with extension .JPG
3. the cropped image will not be deleted by DELETING or UPDATING the avatar
It would be nice if you can take a closer look at these problems. Right now the avatar funtion is a little bit useless for me.
Try current dev version again. Current dev version convert all uppercase to lowercase in filename. And if you have issue with filesize, try to increase your server limit by increasing value of ‘post_max_size’ and ‘upload_max_filesize’ on your htaccess file.
