I'll admit it's my fault for using parentheses in a filename, but the damage has been done. With my previous host, the server handled such files ok.
Here's one of those files:
With DreamHost, the converted version of that url gives a 404 error. Apparently, the forum software here converts the % code of the characters. Pretend that the right and left parentheses are displayed as % 28 and % 29, respectively, but remove the space between the % and numbers due to the software decoding what I entered.
However, the file loads fine with my previous host's server:
Is there something I need to put in .htaccess to make the urls recognized the way they were before?
If context helps, this is the page on which the image file shows up (or is supposed to):
At that url, you could see the url that I referred to in the source.
The above observations are based on using Firefox. In IE, it is able to handle the problematic url and the image shows up fine on the page.
