I've temporarily swapped my 15" alloys for 17". Do I need to realign the steering?

Hi I have swapped my 15" alloys with 17" to paint them but when I swap them back (having only been about 5 days) does my steering need to be realigned? I know if I swapped the alloys and DIDNT swap them back I defiantly would but because I am swapping back to what I initially had after only a few days, do I really need too? 

All help is appreciated! Thanks in advance!

No, swapping alloys shouldn't affect wheel alignment at all.  Swapping suspension or steering parts does.

Thanks Tom!! :)

Will affect speedo reading though

Not if they're the same rolling radius with tyres.
