Ok. So finally understood. I had taken away from the editor all those odd optionbars so I had to add them from Forum control panel. And then I clicked the attachment I downloaded to open in another window (or can I just copy the link without opening? Probably yes.) And then I clicked the add image icon and gave the url of the attached image and finally, finally I managed to get that smaller preview image which I have wondered and envied how others do it.

Edit: WRONG!!! "And I have to remove the attachment from the list so not to attach anything except the url." WRONG!!!

And now I noticed that the image dimensions for download are now 2000x2000 and I also the first time noticed that I can set my own value in the default image viewer and I tried and found out that to downscale to 77% gives just under 2000 the width value.

So now I can post proper competition images in aproper way and now my micro-b scales the full image corretly to fit in the screen when I click it to full size.

Phew! That was a tough one.

This picture is interesting if you know the building behind the wrong parked russian car and the limousine for private parties: SUPO (Finnish National Security Agency).

Edit: Aaaargh!!! I didn't get it. I tried the trick attaching id numbers from the url but it showed the image still big. So then I copied the url of the attached file to "add image" and it showed the smaller image but at the same time also the big image. So then I thought that the image is uploaded to my account and that I can just remove the image from the post and it shows it with the url but NOOOO!

How do you do it? Pichlo? Anyone? I just can't make it happen right. How to get in the post only the smaller image which you can click to get it bigger?
