Dear Reza

Regarding your question, You can create a connection between a master entity and a parametric entity. The parametric entity holds the actual images. Then you can select the file through xpath Or you can also do what you need though SOA Layer.

Here is the XPath statement, where MasterEntity is the name of your Master Entity that has a related attribute connecting to the ParameterEntity (replace with the name of your ParameterEntity).

<MasterEntity.Image> = CHelper.getEntityAttrib("ParameterEntity","id+ParameterEntity", "Imagename = 'SomeNameofTheImage");

In this case the ParameterEntity has two attributes:

1)Image attribute that actually holds the image.

2) Imagename as an example so you can filter and get the appropriate image you need from the ParameterEntity.

You can then drag the Image attribute of Related attribute on the form to display the image.

Best Regards
