Stopped working

This is how it looks for 99% of the images:

So far i have noticed that the watermark was applied to only 1 image:
https://goo.gl/77JmI (This is a Google Search query link, shortened)

Also, it appears that i am not the only one having the problem.

Please kindly check this google image search query: https://goo.gl/Ao0CL

The problem exists on basically many other sites that use the plugin.

If it may be of help, i can only see 4 images in the ~hotlink cache folder now, but they all end with capital .JPG instead of the most files i have which end with .jpg and .png

Hi, sorry for the delayed response, I’ll try to get some more changes to the plugin in the near future … so far I have not had time!
