Go to the plugin Cache section and turn off Assets compression. There is a bug which has been fixed in the update we are preparing right now. It should be live later today or tomorrow if there is need of more testing.
The event images are added from the Introduction tab
About the size. I'm giving you the aspect ratio. The pixels depend on how wide is your container. If the calendar container is 1400px then your image should be 1400px wide.

Thankyou so much for replying . It worked .
One more question is how to change the event content image size ?
Because it is too big .
Please help me .
You can't edit the image dimensions in the plugin. You should prepare your images before upload, we suggest you use landscape formats.

What do you mean by landscape formats ?
Because the image is working like header image of the event for the best results we advice to use aspect ratio 16x9

1. Should i add it from "add images" option / add media option ?
2. 16:9 ratio means it will be 1280 : 720 pixels ?
