Content creation

First of all thank you so much for such a wonderful material. 
I am really greateful how I can give you back for such enormous gift.

i just joined the community and I take advantage to greet everyone in here.

now passing to my topic just  a quick question I have created a content I  drag and drop but I can't remove the background. to be more specific.

I have created a tree where i put apple and my son has to drag and drop them into a basket. but the apples they have a white background as a pictures. not like a fruit in the tree.

Hi, 

I created some stuff in moddle and now I would like to know if it is possible to open it in my personal H5P account.

Regards!

Hi,

I am looking for a way to change the last digits of h5P embed id that is generated automatically in the Wordpress environment upon content creation. Currently the id's follow a set sequence 1,2,3,4,...etc. which makes it easier for the students to guess the other content from source links in iframe. I am giving a sample embed code that is generated in wordpress. Can we change the bold number 1 to something else?
