pictures uploading but not showing up

I think this is a stupid question, but I can't figure out what I need to do to make it work. My images are being pulled from the database. My pictures are being uploaded and separating into the two sizes that I need. I have 2 different rows in my table - one for smallImg_used and the other for largeImg_used.

How do I - after the images are uploaded to the folder- make the images point to those different rows in the table and show on the page? When I insert a record, it shows my name and description as I inserted, just not my images that I uploaded. The fields are actually blank. I even named the id and name after the row name. I've also tried playing around with the lighting bolt inside the actual dfp configuration.

I'm using php and mysql. I also used the DataAssist wizard to create my results/insert/update/delete pages. I deleted the text field for my thumbnail and inserted a file/upload input type and then put the dfp2 upload to it.

Thanks for any help!
