Module Error Message: Can anybody help?

Hello Everyone, 

Recently, I have started seeing this error message on my Drupal Evolve Theme. Can anyone recommend how to solve this problem? 

• Notice: Undefined property: stdClass::$image_dimensions in dexp_animation_preprocess_block() (line 407 of/home/mehtesham/public_html/sites/all/modules/drupalexp/modules/dexp_animation/dexp_animation.module).
