Template image sizes
Theme uses script that auto scale images so it doesn’t define any sizes of images.
For WooCommerce you can change images sizes in WooCommerce → Settings → Products → Display → Product Images. After this you will have to rebuild thumbnails for it.
For this task you can use plugin, we advice AJAX Thumbnail Rebuild. Just install plugin in your WordPress & activate it. You can then rebuild all thumbnails in the tools section (Tools → Rebuild Thumbnails).
Theme support Youtube and Vimeo videos, and also HTML 5 types.
For YouTube best to use links as : https://www.youtube.com/watch?v=JByDbPn6A1o
For Vimeo best to use links as: https://vimeo.com/12280336
Any other link will be treated as HTML 5 video. Browsers that understand the HTML5 tag will display MPEG/H.264 (.mp4) files, VP8/webm (.webm), or Ogg/Theora (.ogv) files. Other browsers can use Flash to play the .mp4 or .flv.
