ad button and image not showing up

Hi,

I installed ad button plugin and I had not problem. I configured the settings and the image URL to my server, the image appears as X and the title (the image does not appears) I tried with the plugin image, it worked when it was stored on the plugin creater server but as I moved and point the url to my server, it appears the X with the title of the image, no image.
