Using 404 caching for images

I get the following message in my error log
File does not exist: domain.com/img/1
What could be the issue? The files are not cached in the /img folder..

did you put the .htaccess in place ( or the equivalent of you are not using apache)

Thanx for all the info people !!

I got it working so far with one little problem.
I am using more then one feed and only 1 merchant feed shows no picture.
The merchant folder is created but no images are saved in that folder.

The feed is from Commission Junction and the merchant is TrendTimesToys.

I have been spending day's trying to figure out why it works on only most of the feeds.
Any help would be apriciated.

Greetz,

Sander.

some probable causes, maybe one of thee applies:

• the images are very large
• the images are buggy
• the remote server blocks the default php user agent
• the remote servr blocks your ip for flooding

any of these applies? Any information in the error log.

Can anyone help on using webp format for the 404 caching images without using db. When usedb=true there is no folder/file created and cant figure out why. Any help is appreciated. Thanks.
