Dear all,

I have a big network of size N and want to display each node by images( different image for different nodes). How can I add all those image automatically just by providing its path. I can manage to add image one by one by [Image/Chart 1] button but that is not feasible for a big size network.

Please let me know, if any of you having any simple idea.


regards
Ashraf

Sure, just add a String column to your node table, then add a URL to each image in that column.  Then use Image/Chart and set up a Mapping for that column and use a mapping type of "Passthrough Mapping".

Dear @Scooter Morris
Thanks for your response. I tried to follow your steps but still not succesful to all image links. I don't have any doubt on your instruction, possibly I'm doing some silly mistake in my steps. Toy example of my steps are following:


[edgefile.csv] %file name
Source,Target,Weight
1,2,1
2,3,6
1,3,7
2,4,2
4,5,1


[urlfile.csv] %file name
name,Image URL
1,/home/compbio/Desktop/imagefile/im001.jpg
2,/home/compbio/Desktop/imagefile/im002.jpg
3,/home/compbio/Desktop/imagefile/im003.jpg
4,/home/compbio/Desktop/imagefile/im004.jpg
5,/home/compbio/Desktop/imagefile/im005.jpg


also tried by:
[urlfile.csv] %file name

name,Image URL
1,1: Image: /home/compbio/Desktop/imagefile/im001.jpg
2,2: Image: /home/compbio/Desktop/imagefile/im002.jpg
3,3: Image: /home/compbio/Desktop/imagefile/im003.jpg
4,4: Image: /home/compbio/Desktop/imagefile/im004.jpg
5,5: Image: /home/compbio/Desktop/imagefile/im005.jpg

in all cases, Mapping Type: 'Passthrough Mapping'


Please, help me to find my mistakes!


regards
Ashraf

You need to put in a URL, not a path.  It may work with a file url:
file:///home/compbio/Desktop/imagefile/im001.jpg
