2 calls to _itweak_upload_preprocess_files()

itweak_upload_comment in ./itweak_upload.module

Implementation of hook_comment(). Add attachments to the comment on view or preview. Here we intercept attachments from comment_upload.module, and render them ourselves. It is critical to be before comment_upload.module in {system} (lower weight).

itweak_upload_nodeapi in ./itweak_upload.module

Implementation of hook_nodeapi().
