An album creating app obtains model templates forming a model album, candidate images to be used to create an album, and a candidate template usable as an alternative template to the model templates. For each model image included in each model template, the app selects a similar image being one of the candidate images which is more similar to the model image than the other candidate images. Then, in a case where a similarity between the model image in the model template for a processing target and the selected similar image is smaller than a predetermined threshold, the app determines which of the model template for the processing target and the candidate template is to be used as a template for processing of the processing target. Then, the app creates a layout by placing, on the template determined, an image similar to an image placed on the template determined.
