Opera 9.23/8808 (Win32) on WinXP:
While running a file cleanup on my C: drive to reduce wasted space,
the analysis program found a pretty large folder here:
C:\Documents and Settings\username\Application Data\Opera\Opera\profile\skin
I would have thought such a folder might contain only Opera skins,
but what I find is that every image which I have ever chosen to display,
even as a test, as my Desktop background, is still saved in that folder,
as a large ".bmp" file!
I had gone around looking for images, trying _hundreds_ of these things;
of course, Windows promptly forgot about the last one saved,
every time that a new one was saved, not collecting them
into a set of future choices, so I had presumed that each new image
stored would have replaced the previous one.
Does Opera have some feature that allows you to review all of these
bitmap images, to set them again as Desktop "wallpaper"?
If not, what's the use of stashing every image away, in a well-hidden
location where it will likely never be found again by anyone,
simply occupying an ever increasing amount of disk space?
If there's a reason to keep them, why not advertise to the user
that they exist? If there is no reason to keep them in an accessible manner,
why not overwrite or delete the previous one upon storing each new one?
It looks as if the present system was designed solely so that the name of the
file would be seen in Windows, when showing the current desktop wallpaper name,
rather than a constant name like "Netscape wallpaper" that said old browser
always re-used each time; unfortunately, this also leads to unsuspectedly
piling up trash, leaving no clue behind, doesn't it?
FYI, Windows 2000/XP/+ users
who would like to keep a large collection of wallpaper images,
in far less space, could consider putting ".jpg" (and similar) image files
into "%windir%\Web\Wallpaper" - which does not require expanding
all of them at once into permanent ".bmp" files,
and which also lists them in the standard place:
"Display" properties (or control panel) > Desktop
