postgreSQl and images

Hi, I create a table with some large object (ref: OID) to store some images. When my PHP will display some data, it will also display the images stored as OID. However, i've read that before i must restore the image by exporting them to local (on server) file. isn't it easier in this case, to simply store the path and file name of file to DB and just read the data to display image on PHP pages ? what is the purpose in this case to store image a bytea / large object ? moreover, how my php code will load image from DB and stored there as OID ? isn't it too much complex in comparison with just storing path and name of image ? thanks a lot, Al.
