So I've added a plugin to Lackey and the creator of the plugin did not include pictures of the cards. just a little text box giving the card info. I'd like to add my own pictures if its' possible. How would I go about doing this?
look at the plugin and if it defines pics then yes if not then you will need to add them and there is a tutorial to help with this.
If it uses card image files, and you just don't like the card image files it downloads:
First download them all, so you have a complete set and know how the files are named. Then edit the images however you want them. Of course this won't affect what your opponent sees, but you will see your custom card images. If the plugin was made correctly, your card images will not get altered when you update, except cardback.jpg and spawned.jpg.
Or you can just tell the plugin maker about them and he may add them as the official card images.
