I just made a chance to the server I wanted to let you know about.
In the past, if you clicked "Insert Image" button and then selected a file from your computer, it created a very small thumbnail, around 100x100, which in many cases was hard to even tell what the image was.
I've change that, so now, if the image is smaller than 300x300, the image itself will show in full, and if it's over 300x300 in size, then it will create a 300x300 thumbnail, and you can click it to see the full image.
See this as an example. This is a 300x300 thumbnail that was created, but if you click it, it will show the full size image.
