Is there a standard image size for this theme?

Hey SpyderSpy6!

In the themes functions.php file all of the thumbnails that the theme tries to generate when you upload a photo are listed out:

$avia_config['imgSize']['widget']                                  = array('width'=>36,  'height'=>36);                                                // small preview pics eg sidebar news
$avia_config['imgSize']['square']                              = array('width'=>180, 'height'=>180);                                 // small image for blogs
$avia_config['imgSize']['featured']                          = array('width'=>1500, 'height'=>430 );                                                // images for fullsize pages and fullsize slider
$avia_config['imgSize']['extra_large']                          = array('width'=>1500, 'height'=>1500 , 'crop' => false);        // images for fullscrren slider
$avia_config['imgSize']['portfolio']                          = array('width'=>495, 'height'=>400 );                                                // images for portfolio entries (2,3 column)
$avia_config['imgSize']['portfolio_small']                 = array('width'=>260, 'height'=>185 );                                                // images for portfolio 4 columns
$avia_config['imgSize']['gallery']                                  = array('width'=>710, 'height'=>575 );                                                // images for portfolio entries (2,3 column)
$avia_config['imgSize']['masonry']                                  = array('width'=>705, 'height'=>705 , 'crop' => false);                // images for fullscreen masonry
$avia_config['imgSize']['entry_with_sidebar']         = array('width'=>710, 'height'=>270);                                 // big images for blog and page entries
$avia_config['imgSize']['entry_without_sidebar']= array('width'=>1030, 'height'=>360 );                                                // images for fullsize pages and fullsize slider

//overwrite blog and fullwidth image on extra large layouts
if(avia_get_option('responsive_layout') == "responsive responsive_large")
{
        $avia_config['imgSize']['gallery']                                  = array('width'=>845, 'height'=>684 );                                        // images for portfolio entries (2,3 column)
        $avia_config['imgSize']['entry_with_sidebar']         = array('width'=>845, 'height'=>321);                            // big images for blog and page entries
        $avia_config['imgSize']['entry_without_sidebar']= array('width'=>1210, 'height'=>423 );                                        // images for fullsize pages and fullsize slider
}

In general bigger is better since getting sized down wont cause loss of quality where stretching to fit will.

Cheers!
