does it mean "is this an issue that prevents you from using Firebug on

Indeed, that's rather what I meant :).
For your need you can use NetExport (Firebug extension maintained by the
Firebug Working Group): http://www.softwareishard.com/blog/netexport/
And maybe automate using Selenium:

When you get the HAR files, which are JSON files, you can query them to
extract the URL of the images you want (with some program you write).

Hmm... even after googling the phrase "blocking issue" I'm still not
exactly sure what it means... if I were part of the Firebug
development team, I guess it would mean not going forward with a new
version/release until that bug were fixed (?). But since I'm not part
of that team... does it mean "is this an issue that prevents you from
using Firebug on your project" or something like that?
Anyway, no, it doesn't stop me from using Firebug. Perhaps (at the
risk of trying everyone's patience) I can describe what I'm trying to
do...
I'm developing some web pages with a large number of images on each
page. I'm working on some PHP + JavaScript to pre-load (download to
the browser cache) some of the images that will likely be called on
subsequent similar pages that the user is likely to navigate to, which
involves making predictive guesses. I keep fiddling with the
pre-loading code and then reloading the browser, over and over, and
each time I need to see which images do or do not get downloaded from
my development server to the browser. There's only a few images I
actually care about on each page, but they tend to get buried in the
long list of hundreds of irrelevant images. It really slows me down to
have to hunt through the list each time I make a code change and
refresh the browser.
The important/relevant images have two distinctive features: their
filenames always contain two consecutive numerals, and they're the
largest (filesize) images in the list. I don't really care whether I'm
observing them as they actually enter the cache, or observing them
simply downloading (after I flush and disable the cache) -- that
doesn't matter -- I just need to know whether they were called from
the server, or not, each time.
I've tried using Firebug's Net panel, and various Firefox extensions
like Live HTTP Headers, HttpFox, CacheViewer, and similar, to generate
a list of currently downloaded images. They're all very awkward to use
in this way, for various reasons, and I've been unable to find
anything that can show me a concise view of only what I want to see.
So far the best (strangely enough) has been the Network tab in IE's
built-in Developer tools, but that's not great either, plus it's
awkward because I run IE/Win7 within a VM on my Mac.
I'm surprised there isn't some tool (or maybe there is?) that can
filter out (hide from the list) everything that's loading into the
browser, except for what matches a regular expression. That's why I
was playing with the regexp search in Firebug's Net panel... but even
if it worked, it looks like it would at best only /highlight/ items in
the list (which I'd still have to scroll down each time to find), not
actually filter out everything else as I'd prefer.
Sorry for the lengthy description. Any suggestions would be very
welcome. Thank you.
