By default, spaces in file names are automatically replaced with a hyphen. Is it possible to change that default and insert an underscore instead?
Yes you can. Open the save to web dialog box. Look in the upper right hand corner for a small icon that looks like a down arrow and some lines. Click this to open a menu. Select edit output settings. Change the drop down button from HTML to Saving files {or click the next button until you get the saving files on the button just mentioned}. Change the hyphen to the underscore that you wanted. Click OK.
Thanks for the response, Silkrooster. I already tried that but it
doesn't seem to work. I've gone a step further than your advice and
saved the settings as default.iros. I'm using a file *test test
test.jpg* and I want it saved as test_test_test.jpg. Photoshop keeps
coming up with test-test-test.jpg.whatever the output settings are.
Can I edit the .iros file directly?
