With a static picture on a web page (Browser Active), SELECT image with the RMB.
This brings up a Floating Menu showing:
Flush image
Reload image
Save image
Show image
I have TWO further options:
AWebDL image
ImageToy
but its likely these are customizations.
Anyway, SELECTING Save image brings up the usual Save- Volumes- Parent- Cancel REQUESTOR.
IF the image is a LINK, there are more options in that Floating Menu:
Open link
Open link in New Window
Load link in background
Download link
Add link to hotlist
AWebDL link
° When the image opens in its own window, I take note of the title Heading and use a Directory Utility to COPY that image from RAM:T/ while the Pic Window is still open.
° To extract the URL from a pic window I FIRST choose 'Open link in New Window' and SELECT that empty AWeb Window behind the Pic Window -- choosing the Menu 'Control/Copy URL'.
And yes, it can be possible to track down an image in the Cache.
