All pics should be adjusted for its color, iso, etc. In the end each of them should look in “one” style (corporate identity). Please try to include our logo color in the pics (blue and violet):
2 x cover pics for Facebook: background it’s almost empty now and the slogan “make a wish” should be visible elegantly. Maybe you have a good idea. If not, see attachment. The logo could be again on the left side, maybe small and not so big.
5 x 1200x444 pixel, logo to be added on the left
5 x 1200x628 pixel, logo to be added on the left, separately text in a <button> to write: Jetzt ein Produkt wünschen! So everyone can just click on the pic.
Two pics are the same thus you have to refine only one pic and afterwards you can adjust the size of the other one.
Please let me know how much time you would need.
