How do I get the proper dimensions of Unity image assets unpacked with Asset Studio

[monlupin]

could you provide the image? depending on what its like you may want to run it through something like kuriimu2. what does assetstudio say the size of the image should be? up in the corner of the preview it should have a bit of text saying the height/width
you could also futz with the export settings, but it may not be an export issue? under options > export options
