I've got 1 block which has random images in them (coming of the XGallery module). I want this block to be without any theme-stuff. So no borders...

Is there a way to do this?

not without a lot of editing in the templates. The block container layout is defined in the theme.html, and goes for either all or none of the blocks. You can put the container layout in the block templates themself, butthat means you will have to edit every block you sho on your site to add the container layout to the blocks.

So there is no easy way to do this, I'm afraid...

Herko

actually you can try do this....

step 1
create the block in block admin with a unique name title example "gallery".

step 2
edit yours themes "theme_blockcenter_r.html" and amend it to this code(themes example is x2t):

<{if $block.title =="gallery"}>
<{$block.title}> ///this is to call to block gallery
<{$block.content}> ///amend as you wish
<{else}>
/// this is for normal block
/// amend as you wish


<{/if}>

step 3 upload "theme_blockcenter_r.html"

i have use this in my site and it work perfectly and i can change any block themes without many modification.

Thanx SGSHELL!

your sollution worked, even solved my other prob with bg-colors with it!
