An interesting mono compressor/limiter board from Greece

how do you post them pictures?.. I tried using html and got a blank page

It's directly below the comment input bucket when entering a comment and the option to select is "Full HTML" to get standard HTML tags to work.

Also consider resizing the image with the height="###" width="###" specifiers within the image tag, it helps the image fit in the comment section a bit better.

I usually shoot for a width of around 300 px and whatever height is needed to maintain the proportion of the original.

The Align="left or right" specifier in the image tag can be fun too.

I keep looking but don't see option as you describe.
The only thing I see under the comment bucket is a link for "More information about formatting options", and a save and preview button.
