Dynamic Images

I'm building a site that requires images to be placed into a table
dynamically - the name of each image is drawn from a database reference.
(e.g database entry is "images/image1.jpg" etc). The problem is that when an
image is dynamically inserted in this way (infact its only the location of
the file thats dynamically rendered - not the image itself), i have a 2-3
pixel gap at the bottom of each image. Non dynamically attached images do
not show this behaviour. - I dont understand why this should happen.
I'm using asp 3.0 with vb-script and the image entry is expressed such,
<img src="images/mem_img_sml/<%= rstSearch.Fields("small_img").value%>.jpg"
border=0 width=60 height=60 />
