I just Installed this package https://packagecontrol.io/packages/Hover%20Image%20Preview with package control in sublime text 3
now I want to configure it as said in the link, can anyone tell from where I can configure the width and height???
this package do not show up in Preferences>Package Setting
THANKS...
I've been there, it took me a while until I fully realized how Sublime settings work and being changed.
A general suggestion that might help with this issue (and many other you might encounter while working with Sublime):
Read this page carefully, esp. SETTINGS FILES section, pay special attention to the hierarchy of the prefs files.
For me it was a true revelation that set thing straight for good.
Hope it helps you too
