There are a huge number of these. Below are the most common.
Can't open display
X11 must be running. If running tnimage remotely, xdm must be running on the host machine. It is also necessary to have the remote computer's name in your xhosts by typing the following local command:
xhost + Remote-system-name
fcolor 0 is already used by another application
fcolor is now set to 39
bcolor 35 is already used by another application
bcolor is now set to 40
This message is harmless and means that the foreground and
background drawing colors have been taken by
some other program and can't be used. They have been automatically
remapped.
Can't create icon
Not allowed to create a 32x32 icon!
These messages are harmless and means that your Window manager
has some limitation that prevents the creation of an icon of the proper
size. Iconized images may look funny.
Less than 32 free color cells available
Using modifiable colormaps
Some other application(s), or the Window manager itself, has grabbed most or
all of the colors. Tnimage has automatically switched to ``colormap mode'' to
obtain good image quality. Flashing may occur if the mouse is moved from
one window to another. It is recommended to maximize the tnimage window to
prevent this. Alternatively, exit tnimage and close Netscape or other
imaging programs and restart tnimage.
This message occurs frequently in Solaris, because of the Window Manager.
No visuals found
No appropriate visual
X11 is running in an unsupported screen mode.

Please send a complete bug report (see Sec. 1.5) to the author if any of these messages or similar messages occur.
Can't allocate colors
Another application may be using all the available colors; or another copy of tnimage may be running. Try closing some applications.
virtual memory exceeded in new()
The image appeared to be a valid image file but was actually junk and sent impossible coordinates to tnimage, causing it to crash. Please send me a copy of the offending image file so future versions can check for it.
Can't resolve symbol ``__register_frame_info''
The version of tnimage you are using was dynamically linked to libc5, but your system has glibc. Obtain version 3.0.0 or higher of tnimage, use the statically-linked version, or recompile tnimage on your own system (Note: to recompile tnimage, you will also need a glibc version of Motif).
8-bit TrueColor mode, yuck! tnimage does not run
well in 8-bit TrueColor mode, which is the default for VNC. It is recommended
to start vncserver with the ``-depth 24 '' option.
