Unable to locate location of images stored in SE78

Hello Experts,

In one of my custom webdynpro ABAP component they are displaying images based on the dropdown(value selected)

I am unable to locate the location from where the images are fetched in se78.

Description about the issue:

The images content(data) is stored in one custom table and  images are fetched from se78 tcode.

My issue is when user selects value from dropdown some times images will not display.

Now i want to know where the images are stored and download all the images to my desktop.

I want to know another  way to display images based on the selection of drop down values.

Thanks in Advance.
