How to define maximum size for ALL Dial thumbnails (at once)?

[tobwz]

I have setup a number of Dials for GSD in Firefox browser on windows.
Most of them retrieved their corresponding thumbnails from public library. A few more are from local image file.

They appear rather big.
Too big.

How can I resize all Thumbnails by let's say 20% (so that their size is 80% or the current size)?
If necessary I could specify a maximum height/width size in pixels.

Can I do this for ALL thumbnails at once/in one step?
or do I have to do this manually for all my dials :-( ?

Hello,
That depends on what exactly are you trying to achieve...
Usually, changing group layout (in "Edit group" window) helps resizing dials (and their thumbnails).
But if that's not enough, then changing "Thumbnail padding" in the Edit dial / Visual tab, is the only way.

However, if you really want to change the padding globally, you could use Custom CSS style.
For example, paste this code to the Options page / General / Custom CSS styles:

.dial_thumbnail { padding: 20% }

This will set global padding for all thumbnails and you will be still able to override it on specific dials through the Edit dial if needed.
