image change issue

So i just bought the plugin installed it into my server uploaded a image to check it out realzied the image was to be pixelated fixed the image with a newer one with and now it won't let me change the image even after 0.reloading the plugin even after i changed the png file name with the new one it still displays the original one i first loaded up 

Good morning, this isn't a plugin issue, but a problem with the image management system (ImageLibrary). 

This explains exactly what's happening:
First PNG uploaded -> ImageLibrary saves it under "afk_screen" -> you replace the PNG or the URL -> the plugin reloads -> ImageLibrary says: “I already have ‘afk_screen’” -> the old image remains.
Renaming the PNG file doesn’t help either.
For example, if you change from
afk.png
to
afk_new.png
but continue to use the same ImageName = “afk_screen” in the configuration or code, ImageLibrary doesn’t care about the filename. The internal key remains “afk_screen.”

You can temporarily fix the problem by deleting the /data/ImageLibrary folder once (be sure to deactivate the plugin first). This shouldn’t result in any data loss; the next time you load the plugin, your ImageLibrary will be cleaned up, and unnecessary images that aren’t being used will be removed.
