QlikView uses a Bundle Info Load to load images into QlikView. This requires that the images are stored in a folder.
BUNDLE info LOAD
User, // being the id in your case
'images\' & User & '.jpg' as UserPicture // assuming username.jpg are your file names
Next, when you create your listbox , in the Presentation properties, representation, select "Info As Image". Set Image formatting, probably to "keep aspect".
But i cant get the images in folder other than manually putting these in images any help would be highly appreciated.
