You can find a very good guide about adding logos to your channels in the wiki:
TVChannelLogos - MediaPortal Wiki Documentation
I'm feeling a bit stupid at the moment, because I tried that and it doesn't work for me. I'm using the latest release (1.0.0 RC2). Firstly there was no Thumbs\TV\Logos directory in either \Mediaportal or \TVServer directories. So I created on in \MediaPortal.

I'm feeling a bit stupid at the moment, because I tried that and it doesn't work for me. I'm using the latest release (1.0.0 RC2). Firstly there was no Thumbs\TV\Logos directory in either \Mediaportal or \TVServer directories. So I created on in \MediaPortal. Tried a range of CAPS options on the naming of this directory. Also looked for the \cache directory but don't see one...... I tried logos with PNG extensions and without......The example image I was trying is square and has a very simple name 'ABC1' which matches the 'Name' in MediaPortal Setup -> Television -> TV Channels.
Has something changed for Mediaportal with TV server?
Is the Cache in a different place?
Should I be doing this in the TV Server instead?
