Please can you clarify the limitations on the dimensions of images that can be uploaded? eg. for the t-shirt theme what are the restrictions or ideal photo sizes? Or for the theme with a main image, what are the image recommendations?
Also, does the software auto re-size if the image uploaded is too large?
Good question. The software recommends 300 x 225. I've submitted that size and larger and for both, it resized the images to fill the allotted space for the ad boxes.
