Hi inickqc,
You are right hex2rgb function is already defined in your theme folder in ait-functions.php file.
To resolve this error please follow these steps:
Step-1: open your plugin directory
Step-2: Open responsive-photo-gallery folder
Step-3: Open file responsive-gallery-short-code.php in any editor
Step-4: find these code at near line no. 28
function hex2rgb($hex) {
$hex = str_replace("#", "", $hex);
if(strlen($hex) == 3) {
$r = hexdec(substr($hex,0,1).substr($hex,0,1));
$g = hexdec(substr($hex,1,1).substr($hex,1,1));
$b = hexdec(substr($hex,2,1).substr($hex,2,1));
} else {
$r = hexdec(substr($hex,0,2));
$g = hexdec(substr($hex,2,2));
$b = hexdec(substr($hex,4,2));
}
$rgb = array($r, $g, $b);
return $rgb; // returns an array with the rgb values
}
$RGB = hex2rgb($WL_Hover_Color);
$HoverColorRGB = implode(", ", $RGB);

Step-5 replace above code with this code
<blockquote>function weblizarhex2rgb($hex) {
$hex = str_replace("#", "", $hex);
if(strlen($hex) == 3) {
$r = hexdec(substr($hex,0,1).substr($hex,0,1));
$g = hexdec(substr($hex,1,1).substr($hex,1,1));
$b = hexdec(substr($hex,2,1).substr($hex,2,1));
} else {
$r = hexdec(substr($hex,0,2));
$g = hexdec(substr($hex,2,2));
$b = hexdec(substr($hex,4,2));
}
$rgb = array($r, $g, $b);
return $rgb; // returns an array with the rgb values
}
$RGB = weblizarhex2rgb($WL_Hover_Color);
$HoverColorRGB = implode(", ", $RGB);
