3 tier architecture query ? image ?

Question

Hi

 

Well lets say i created a windows forms application with slide show (3 TIER ) . .

 

What i need is when we end user access the app to begin slide show .. The images will roll accordingly .. But were will the image is stored ?? which tier UI OR DATA OR BUSINESS LOGIC TIER ???? .. I hope it will be Data Tier in table i created image DATATYPE .. But what happens when i delete file from where i uploaded will still the file accessable .. i.e under some folder of DB the image gets stored or what happens ..

 

i have many questions regarding this but first let me get clarity n this :) Ty
