[mythtv-users] Mythweb Channel Icon problem

Thanks for you your replies. I am running apache2. As far as I can remember
almost everything (apart from the TV card driver) is installed using
apt-get install. However I have been using myth since 0.21 and Ubuntu 8.04
LTS, and until recently 0.25 on 12.04 LTS. I normally do an upgrade, then
copy the config files and then do a fresh install, but is possible a few
sim links or something got messed up on the way.
This has been a problem for me on just one channel - BBC2 (I am in the UK),
I think that recently I switched from a regional variation to a national
variant or vice-versa. However, I have replicated this issue for any new
channel icon that doesn't currently have an image in the image cache folder.
I do have a folder /mythweb/data/tv_icons, but it is a link to the
image_cache I mentioned above. Maybe next month I will wipe everything
again and reinstall. (Except everything else is running better than ever at
the moment so maybe I won't.)

Bil, myMythServer:6544 - WOW!, I haven't seen that before. All images work,
but then all images are working as I manually inserted an image into the
mythweb folder. The link you suggested didn't work, but some pages need a
password (no idea what that is) so that might be the problem. I can't see
any links when I hover.

Yes Jay, I thank that summarises my problem, except that it is not an image
- and is only 44 Bytes. So the daemon is running as a file appears, write
permissions must be okay as something is written, the folder images are
coming from is readable by anyone, and these display in mythfrontend and
mythbackend-setup. I have tried both png and jpg and neither work.
Gary thanks for the link, but I have had no problems with mythtv-setup, nor
mythfrontend, my problem  is with mythweb, which seems to use a different
