Changing the default portfolio gallery image size

The default image size for the Portfolio Gallery Template in the Dandelion theme is declared in the functions/portfolio.php file, starting on line 68:

Two column layout:

$pexetoImageSizes[2]=array('width'=>427,'height'=>230);

Three column layout:

$pexetoImageSizes[3]=array('width'=>272,'height'=>183);

Four column layout:

$pexetoImageSizes[4]=array('width'=>195,'height'=>130);

If you would like to modify the default size, just change the width/height value for the relevant column layout.
