Auto-upload image feature with image browser module (e.g: Image picker)
Not sure it would help, because I don't know what you mean by "auto" uplaod, but here is the configuration I use:

FileField Sources module
https://drupal.org/project/filefield_sources

with IMCE module:
https://drupal.org/project/imce

FileField source is pretty usefull to present user a set of upload options for a single image field.
