switchimage implode() error

[hefestus]

First!

I try to adjust hight and width parameters by
{phocagallery view=switchimage|basicimageid=172|switchheight=240|switchwidth=320}

i get 640x480 in div (overlapping by menus)

Warning: implode() [function.implode]: Invalid arguments passed in /home/milan/public_html/jtest/plugins/content/phocagallery.php on line 1346

Then:

{phocagallery view=switchimage|basicimageid=183|switchheight=480|switchwidth=640}
default size
same like previous 640x480
and
Warning: implode() [function.implode]: Invalid arguments passed in /home/milan/public_html/jtest/plugins/content/phocagallery.php on line 1346

any advice!
