Although more comfortable with a spanner and mallet than computer, I found the photo process here quite easy to use, and I like TM Img as it keeps all my Morgan photos in the same place. People often ask 'how did you do x,y and z' and I can they go straight to TM Img and find details.
There are other forums I use that you can add photos directly, but they usually have a file size limit, so I have to faff around re-sizing photos before I can upload. No worries with TM, upload the photo, paste it into the message.
