General :: Creating Photo Albums?

I just transferred a bunch of pictures (over 2000) from my ipod to my mytouch 4g slide. I had them all in neat little albums on the ipod and i would like to do the same on my phone. Problem is i cant figure out how, other than putting the files into separate folders on my sd card, which i don't like because i like to have a general folder of all of them together with separate albums for specific things, and sometimes a picture would go into more than one album. Is there an app or a way to do this on my phone, I don't mind if the app creates copies of my pictures as long as the original files are left untouched. And is there a way to organize my pictures by name rather than date? Because when I transferred them it don't keep date it was added but rather the date i copied it, and when organized by name its correct because of the numbers in the file name.
