The slideshow gadget in Blogger is quite small and may look minuscule in larger width templates. If you have a large width sidebar and wish to increase the size of the slideshow within it here is how you can do it.........

Step 1. Add Slideshow Gadget to sidebar :

  1. Login at
    Click Layout link under Blog Title on Dashboard.
    On Add Page Elements tab click 'Add Gadget' link.
    In popup window click 'Slideshow.
    Configure your slideshow.
    Click Save button below.
    View Blog.

Step 2. Find width of your sidebar.

To increase the width of the slideshow you have to first find width of the column containing it. To do this go to Layout----->Edit Html subtab. In Template Code box scroll down to the CSS code for the sidebar which may look like this :

#sidebar-wrapper {
width: 220px;
float: right;
word-wrap: break-word; /* fix for long text breaking sidebar float in IE */
overflow: hidden; /* fix for long non-text content breaking IE sidebar float */

See the number in the width line '220px'. That is the width of the sidebar. You cannot have your slideshow inside the sidebar with more width than this or else it may break the template and your blog sidebar may fall down below the posts column.

Step 3. Define slideshow size in CSS part of template.

The last step is to define the new size of the slideshow in the CSS part of the template. In your Template Code box paste the code given below immediately above the ]]></b:skin> tag :

.slideshow-container {
width: 200px !important;
height: 400px !important;

Preview and adjust the width and height numbers. Save Template. View Blog. Enjoy slideshow!

Did you clear cache after changing and saving settings?

Is there a way to enlarge it to 900pix wide and put it in the main header area?

Vin said...


You have to first increase width of header.

Then create a Add gadget link in the header and then add a HTML gadget there.

Then paste the slideshow code there and modify it.

Hi Vin,

I've put the slideshow gadget in the header of my blog.
But the quality of the pictures are really bad.
I edit the size of the slideshow to 649px x 136px in the HTML code... and so are the pictures form my slideshow.
I've tried at 72 and 180 dpi but still the pictures are pictualized.
You can have a look to my test blog...
I've been using Picassa for the slideshow.
Looking forward if you have any tips for me.

Hi Vin,

I'm wondering if there's a known issue with IE that makes the images of the slideshow so tiny. The size of my slideshow is perfect in Firefox and Chrome but it's like 10x10px in IE8. Do you have any workaround for this?
