Hello,

Try this,

Your image should be saved inside yourmodule/static/src/img/image name

<img src='/module name/static/src/img/image name with extention' style="max-height: 45px;"/>

In case if you have stored your image in a binary field then use this,

<img t-attf-src="data:image/*;base64,{{o.field_name}}" style="max-height: 80px;max-width: 145px;padding:2px;" align="center"/>

Thanks

Try this,

<img t-attf-src="'/my_module/static/img/img.png'" width="100%" height="100%"/>

or


<img t-attf-src="data:image/jpg;base64,{{ model.some_logo }}" align="left" height="65" width="65" style='margin:0px;padding-top:0px;' />
