You can post them via an external site. This is how I do it:
First you open a free account on
https://imgbb.com/
Then you create a new album on this website.
Make it “private/everyone with link”
Upload a photo like this:
- First hit “upload”, then “browse on your computer”
- Choose your photo
- Hit “upload”
Once uploaded hit “Viewer links”. Here you can choose which kind and size you like. I always use “BBCode Full linked”.
Copy the link and paste it in the message box on TOCH. You do NOT have to use the “insert link” feature of TOCH. Just copy the link in the message box.
Hope this helps.
