<div id="album"> [[+thumbnails]] </div>
<img src="[[+image_absolute]]" />
I think the only way of avoiding the use of phpthumb is to use the image_absolute placeholder in your template. I would do:
&containerTpl:
<div id="album"> [[+thumbnails]] </div>
&thumbTpl:
<img src="[[+image_absolute]]">
Remember, don't adjust and use the default template chunks, make your own. This is because the defaults will be overwritten when you update Gallery to a newer version.
