You can use some CSS to change the height and width of the image.
For example: <img style="width: 100px; height: 100px;" .../>.
But to save bandwidth and make the page load faster you should make a smaller resolution copy of the image and use that on your site instead.
I appreciate it jkeyes!, but unfortunately I need more simple, step by step explanation…

As for the future: resize your images BEFORE uploading to your blog.
Google and find free image editor programs, download, learn.
You have the following in your HTML:
<img alt="Jutranja zabava" src="http://damijanganc.tuditi.delo.si/files/2007/02/pict0150.JPG"/>
Change it to:
<img style="width: 100px; height: 100px;" alt="Jutranja zabava" src="http://damijanganc.tuditi.delo.si/files/2007/02/pict0150.JPG"/>
Play with the height and width values until you get a size you like.
