It seems like I need to customize the GUIShop LANG messages with every update.
Very annoying.

Also, with the most recent updates, GUIShop storage process takes about 10x longer than previous versions.

Sorry, the language keys will not be changing anymore after this. So it won't be a problem moving forward. 

Also, that is because the guishop no longer uses a website to grab the images directly from. 
It uses ImageLibrary directly so it would be the Image Library URL hosted by k1llyou which every other plugin uses.
So the first-time processing will always take a while to finish for the first time. 
But after it's done its initial saving of them reload times are almost instant. ( 5 seconds or less usually )
