No pictures, but I have a few, and love the 3" in general.
I have a S&W 65LS which started it for me. I will never carry it, it is in too good physical condition and too valuable for me to feel comfortable carrying it, but it is a fun range gun and I sometimes load it for home defense.
A 3" .38 or .357 is about perfect for carry. The 3" barrel gives the round more velocity vs. a 2" so that the HP will more reliably expand. However, it is easier to carry than a 4". It is quick to draw and very handy. To me, a 3" J frame or K frame is about the perfect carry revolver.
Next, I bought a 3" Rossi 461. I've never carried it though. My 2" Rossi 461 was unreliable (my only unreliable revolver) and would quite regularly have the cylinder bind when shooting magnums, so I never trusted my 3". Then came the reports of it possibly firing when dropped - during the recall, you were supposed to fill out the form, return it to Taurus/Rossi and wait for them to contact you, I sent it in (the form), twice, and never heard from them and now the recall is expired. I will never carry it, and I haven't shot it in 3-5 years, I plan to sell it (disclosing the 2" reliability issue and that it never got the recall fix, so I won't get much money, it will be just to make room in my safe).
I currently have, and sometimes carry, a 3" new model Colt King Cobra and love it. I have a 3" S&W 317 that I don't carry (it is a .22lr), but I love it and may sometime carry it as a BUG just because I want to. I have seriously wanted a 3" Taurus 431 (.44spl) for about 2 decades, though when I finally got one this past autumn it was a 2.5" (I may sell it and replace it with a 3"). My current wish list includes: a 3" S&W 686+, a 3" GP100, a Taurus 856 Defender, and a Taurus 905 Defender.
I am definitely a fan.
