Photoshop Help Plz

[Kelly G]

Hi

i was just wondering if anyone that is good at using photoshop could edit these Hannah Montana pics

So that they say "Happy 8th Birthday Brooke-Ella" on them, i wanted to get it put onto one of those picture cakes at asda for her birthday on new years day

Tnx in advance

EDIT: if these pics are no good i can find more

I find it best on cakes to chop the pictures square then you can put the writing on in the shop after.

Sorry if that's no help LOL, my trial of PS has expired so I don't have it at the moment.
