Saving Pics

you would do it the same way except once you hit save attachment the screen will switch to file manager and you should see something that say for example /mnt/sdcard/My_Images once you see that you can replace the My_Images part if you have a different folder on your phone to save pics and press save and there you have it

 

Mine seems to work fine, but you could try the save mms app

 

you can do like chitownperri said but you can also save it under /mnt/sdcard and then click save, after that go to your pictures and look for sdcard and all pictures that you saved will be in there
