Auto-upload image feature with image browser module (e.g: Image picker) I am using the imagepicker module for browsing the uploaded images, I have tried searching for the auto-upload integration for this module but still no luck.

I am searching for any alternative way if there for similar thing (mainly I require image browser to use the already uploaded images, and implementing the auto-upload functionality on it).

Any suggestion/recommendation would be appreciated.
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.
