The media displayed on the site is only temporary until I can gather my own and I do believe as long as I am not using the material to induce an income, it is not against copyright laws.
Using copyrighted material without the authorization of the owner is copyright infringement whether or not it generates income.

When people do use copyrighted material on their site they ask first get the permission and then use the material, not the other way around.

If it was me and you ask the permission AFTER you already started using my material I would contact your host and make you take the material down.

It is about respecting people's work and have some ethics which is very important if you plan on becoming a breeder.
