Creating presentations using digital media content

A non-transitory computer storage medium encoded with a computer program comprising instructions executable by data processing apparatus to perform operations comprising:

• receiving input to display a plurality of digital images on a plurality of layers arranged over each other in a sequence to create a digital presentation, each digital image having a plurality of features comprising at least two of a size, a color, a rotation, and an orientation;
• analyzing a first digital image to be displayed on a first layer to determine a first plurality of features of the first digital image, the first plurality of features including at least two of a size, a color, a rotation, and an orientation;
• determining that a second digital image to be displayed on a second layer has a second plurality of features with which the first plurality of features is incompatible, the second plurality of features including at least two of a size, a color, a rotation, and an orientation;
• modifying the second plurality of features of the second digital image into a third plurality of features with which the first plurality of features is compatible, wherein a feature in the first plurality of features and a feature in the third plurality of features are dynamically modifiable based on other features of the digital presentation;
• and
• displaying the plurality of digital images on the plurality of layers, the plurality of digital images including the first digital image having the first plurality of features displayed on the first layer and a second digital image having the third plurality of features displayed on the second layer.

A system comprising:

• one or more computers;
• and
• a computer-readable medium tangibly encoding software instructions executable by the one or more computers to perform operations comprising:
• receiving input to position a second graphical element over a first graphical element to create a digital presentation, each graphical element being associated with a corresponding plurality of features comprising at least two of a size, a color, a rotation, and an orientation, wherein a feature in a first plurality of features associated with the first graphical element and a feature in a second plurality of features associated with the second graphical element are dynamically modifiable based on other features of the digital presentation;
• analyzing the first graphical element to obtain a plurality of first features associated with the first graphical element, the plurality of first features including at least two of a size, a color, a rotation, and an orientation;
• determining a second feature that is compatible with each of the plurality of first features;
• applying the second feature to the second graphical element;
• and
• displaying the second graphical element over the first graphical element in response to the input to create the digital presentation, the first graphical element being associated with the plurality of first features and the second graphical element being associated with the applied second feature.
