Therefore i have to use this option "rightclick on the image --> Show picture". This is not comfortable. Is there a way to get rid of? 

If you add images on a page by attachment: and rescale them by its
params then your browser has to read all the mbytes you saved and
rescales them afterwards. Once having them in your browser cache should
speedup the access of the page.

If you want to speedup the load process then you should use images
resized to the width/height you want to display.

So how big in MB are your images?

With arnica you get access also to a new Image macro which creates a
rescaled image from every size you enter in the servers cache dir.
That is loaded much faster because it is stored resized and only this
amount of data becomes send.

Without any param it creates thumbnails by a size of
THUMBNAIL_SIZE = (128, 128)
<<Image(picture.jpg)>>

you could enter a width and a heigth keyword.
