Importing Problems with the WE

[DerChamp]

I make my own map so i made my own Minimap and MapPreview...
They work fine and they have the size of 64 kb and 52 kb...
Now if I try to add one more Model/picture the size changes to 42 kb and 23 kb and the map doesn't work anymore... i have this with every map i made... and when the size changes i have to edit the map with mpqeditor and replace the pictures and models... So now here's the question:
What can i do, that if i import something it works normal ?
