In addition to the ones you mentioned, the following achievements may give you trouble..

I Love Shopping - Buy first Upgrade - if all of the Skylanders already have one+ upgrade

Climb to the Top - Level Up to 10 - If all Skylanders are already at 10

True Portal Master - all other Achievements  - obviously, if you can't get any of the others

Note that you can reset a Skylander to level 1, or transfer it to someone else.  Look under the Manage option in the Menu.

Which achievements are missable if sharing Skylanders between multiple profiles?
I am trying to recover some lost images, and with all the programs I've tried, some of the photos resulted to be in a 160x120 pixel resolution. What does this mean, and is there any possibility to recover photos in original dimensions?

Any help is appreciated.
