: I think there was
: a problem with my Picasa link - tried again below

That link also didn't work on my computer.
Some web hosting sites hide the actual address and name of the image.
I'm not familiar with Picasa, but if you open the picture, then right click and explore your choices, you might find something like "picture info". Clicking that might give you the actual link to the picture, ending in jpg, which you can copy and paste into a ConnYak post or into the "Optional Image URL" box at the bottom of the screen where you compose messages. You can test it to see if it works by clicking "preview" and trying the link.
