Dude, dont take your truck outta there because someones being a dick about it.
Unless you've changed the height of your pics, they're just fine at the height that they're at. 120 pixels is quite within the limits here.
Supersport, you missed his point.
Which appears to be: its easier for the mods to add the option to view or not view sigs instead of having to run through correcting/informing people of the rule.
It'd be easier if you weren't allowed to link to images in your sig but instead upload the pictures to the GPF server which imposes a limit just like it does with the avatars.
However, that increases the bandwidth demands on the server.
That... Is something rocket himself will have to look into.
Edit: Looks like this DOES exist, we just need to disallow images in sigs somehow.
