! this only works on browsers and images where you can right click an image and press a key to select the "copy image url" menu item

usage

• hover the cursor over an image
• press alt + p to have the image automagically downloaded

hotkeys and folders

different folders and their corresponding hotkeys can be set in the ini section at the top of the file.
the format is hotkey = folder

the following variables can used in the folder path:

• a_desktop
• a_myDocuments
• a_scriptDir
• a_userName

supported browsers

• chrome
• firefox
• internet explorer
• vivaldi

to add another browser, add the exe process name of the browser to the ini section and then put the instructions to get the image url at the end of the script.
(or add the details to a comment below and ill update the script)
