Adding a picture as a background of a graph

MFVIT

Dear All,
I wrote the following script. After opening a data table, it takes the data and creates a graph by using the graph builder. Then it loads a picture which has the same name as the opened data table and use that picture as a background for the graph.
In order to make the script work, I had to add to the data table name the file extension .png as part of the name. So I had to name both the picture and the data table by adding .png in their name (the picture file has the extension .png).
For example, if the name of the picture is sample.png, I had to change it into sample.png.png.
 
Of course I do not like this but if I do not make this change jmp says that it can’t find the picture file.
I am sure the problem can be solved in a cleaner way.
Thanks a lot for any help.

Hi,
The issue is that the variable "n" is a string, not an image even after calling the New Image. I have not found a way to convert directly a string into an image but you can create a dummy txtb = Text Box (n), and then get the picture of that object txtimg = tctb << Get Picture, and finally use the txtimg variable as you background.
I hope it helps. Others may have more elegant ways to tackle this.
Best,
TS
