MacOS – find the source image files for the browser checkboxes in Safari

I use Adobe Bridge, which comes with lots of Adobe apps (list, starting at $250).
It does all you want, and a lot of other stuff too.

Some of my favorite features, other than those that you mentioned:

• Full-screen previews
• Powerful batch renaming
• Cache export
• Configurability / flexibility
• Speed

Another option is Adobe Lightroom ($250). It combines a Bridge-like manager with a reasonably-powerful editor.

I realize that Bridge and Lightroom certainly aren't free, but Bridge really is my favorite image manager.
If you want something that's free, the built-in iPhoto app is a good option, although it's far less powerful. It's got some nice features like face recognition and location-based sorting.

BetterSource

It's similar to the view source in Chrome in a lot of ways:

• It has syntax highlighting and line numbers
• It's opened in a tab instead of a window
• Uses the default monospace font specified in preferences instead of Monaco 12

Limitations:

• Line numbers are included in selections
• The source view cannot be opened with a shortcut
• Takes slightly longer to appear than the normal source window

Setting a default zoom level in a custom style sheet

The custom style sheet you can specify in the Advanced tab of the preferences also affects the view source window. I don't know how to target it specifically, but this would apply a default zoom level to both it and website content:

body { zoom: 125%; }

view source in TextMate.scpt

tell application "Safari" to tell document 1
    repeat 100 times
        if (do JavaScript "document.readyState") is "complete" then exit repeat
        delay 0.05
    end repeat
    set src to source
    set u to URL
end tell

try
    tell application "TextMate"
        open POSIX file u
        activate
    end tell
on error
    set f to do shell script "f=`echo " & quoted form of u & " |
    sed 's|.*://||;s|/$||;s|:|-|g;s|/|-|g'`; echo \"/tmp/view-source-$f.html\""
    do shell script "/bin/echo " & quoted form of src & " > " & quoted form of f
    set f to POSIX file f
    tell application "TextMate"
        activate
        open f
    end tell
end try
