Uploader's 'filename' field (auto populated)

<img src='https://asprunner.com/forums/file.php?topicimage=1&fieldname=question&id=4781&image=1&table=forumtopics' class='bbc_emoticon' alt=':blink:' /> I think it's a small thing that some advanced members may quickly recognize.

• I have my images stored on the web server.
  
• db text field "PicturePath" has been manually populated with picture path\filenames. (works great)
  
• dummy db textfield for upload procedure that works fine as well
  What I want to avoid is the user having to type "bla.jpg" in the "PicturePath" field when adding/editing a record. The filename IS populated in a field as part of the upload function, so really, if there is some way to just automatically have that value jump into the database field...I can make this thing work.
  Any ideas?
