Dear Irag10
Please try with my way
Open modules\mod_yt_content_slideshowii\assets\ytc_content_slide_ii.php file find this code:
if (!isset($item['thumb']) && $item['img'] != '') {
$item['thumb'] = $this->processImage($item['img'], $this->thumb_width, $this->thumb_height, $item['id']);
} else {
$item['thumb'] = '';
}
if($this->imagesource == 1){
$item['thumb'] = $item['img'];
}
if (!isset($item['small_thumb']) && $item['img'] != '' && $this->small_thumb_width > 0 && $this->small_thumb_height > 0 ) {
$item['small_thumb'] = $this->processImage($item['img'], $this->small_thumb_width, $this->small_thumb_height, $item['id']);
} else {
$item['small_thumb'] = '';
}
and change to
if (!isset($item['thumb']) && $item['img'] != '') {
$this->cropresizeimage = 1; // Crop Mode
$item['thumb'] = $this->processImage($item['img'], $this->thumb_width, $this->thumb_height, $item['id']);
} else {
$item['thumb'] = '';
}
if($this->imagesource == 1){
$item['thumb'] = $item['img'];
}
if (!isset($item['small_thumb']) && $item['img'] != '' && $this->small_thumb_width > 0 && $this->small_thumb_height > 0 ) {
$this->cropresizeimage = 0; // Resize Mode
$item['small_thumb'] = $this->processImage($item['img'], $this->small_thumb_width, $this->small_thumb_height, $item['id']);
} else {
$item['small_thumb'] = '';
}
)
