Thanks

Its a way to access builtin QlikView Images, they are stored inside the qv.exe file.

Ok, so they are system image files.

Not really. When the QV executable is loaded in memory, a region is reserved for resources that are loaded at the same time from the executable file. Expressions can reference these resources by prefixing them with qmem:. It just means: look in QV reserved memory space.

Note: in good QlikView tradition, a qmem: image reference points to a block of memory, NOT to some file on disk, not even to the executable.

So is it possible to add further images into the space or not?

Thanks

Not to the BuiltIn section, but you can Bundle load some images that you can reference by e.g. 'qmem://ID/A1'

Bundle

The Bundleprefix is used to include external files, such as image or sound files, or objects connected to a field value, to be stored in the qvw file.

If a piece of external information, such as an image or a sound file is to be connected to a field value, this is done in a table that is loaded with the Info prefix. In order to maintain portability, it is possible to include the external files into the .qvw file itself. To this end use the Bundle prefix. The bundled info files are compressed in the process, but will nevertheless take up additional space both in the file and in RAM. Therefore consider both the size and the number of bundled files before going for this solution.

The info may be referenced from the layout as normal info, via the chart info function or as an internal file via the special syntax qmem:// fieldname / fieldvalue alternatively qmem:// fieldname / < index > where index is the internal index of a field value.

The Info prefix may be omitted when Bundle is used.
