Thanks a lot for your reply Iftikhar Arain
So you mean to say it is a security issue and not a specific one related to '#' in my url right? Even I thought the same & did put crossdomain.xml to see if it is working fine.
But the thing is the
issue exist only for those images which have '#' in their url and the other images are loading without any errors. This problem exists even if I put crossdomain.xml in the server of the images
So I think the issue is specific for character like '#' rather than an generic problem. But I am not yet able to find any solution for this
