widget image not centred

Wrap the code of the image like this:
<center>
Your Image code
</center>

thanks for your reply, but the image is not centered inside the border not horizontally but vertically. If you want to have a look here it is

This is an interesting one: it’s the line-height from your theme that’s causing it. You don’t want to change that globally, so if you add a css class like this, it should take care of it:

.shashinThumbnailDiv {
line-height: 1;
}

i will try that. This needs to be added in the css of the theme I’m using?

You can add it to your theme or you can customize the shashin stylesheet – see here for details: https://www.toppa.com/shashin-wordpress-plugin/#stylesheets
