Unable to remove excessive line breaks

While I hear from alot of users that they are unable to produce line breaks in their posts, my problem is in the contrary. My posts show excessive white space around images. A little space would be fine, for breathing room. But the problem is the space isnt always as big.

For every post I visit the html editor, I remove all the line breaks present there, and they are removed from the wysiwyg editor. But in the actual post they are more than present!

for example:
In the html editor I make sure that all the text is directly against the image tag, no line breaks or spaces present. I also make sure image tags are against other image tags if I want them to ‘touch’ each other in te post.
<image><image><image>text<image>

In the wysiwyg editor I see the images with a thin white line in between images. The line is always as thin.

But in the actual post, the images sometimes have one, and sometimes have two line breaks in between them.

How can I get the power of choosing when and how much line breaks are used?
