Embedded images in widgets automatically resize

Im trying to add an image to a widget and would like the image to hit both sides of the widget but for some reason the image is being automatically resized downwards and there are no settings to turn this off. I have trawled the forums for info and found that you can turn off auto resize on embedded images but no nothing about CSS.

Set the width style on the image itself and it should override the automatic resizer. The resizer is there to keep people from blowing up their sites with 1000pixel wide wide images. You can do something like this:

<img src="image_url" style="width:150px;">

That should override the resizer. If  not, you can try:

<img src="image_url" style="width:150px!important;">

downwards and there are no settings to turn this off. I have trawled the forum

 What site are you seeing this on?
