I had a problem of matrix.org images not showing which was fixed by upgrading my matrix server (matrix-synapse) to the version in Unstable. The problem I found affected Nheko and Schildichat on Android.
While it might have been possible to address this with a patch to Nheko and it would be ideal to have Nheko work with all combinations of servers, upgrading to a recent version of matrix-synapse is a good option. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
