According to example configurations, a digital asset manager receives a digital asset. The digital asset manager generates multiple sets of thumbnail data based on the digital asset. Each of the multiple sets of thumbnail data can be encoded to support display of a different thumbnail resolution of the digital asset. The digital asset manager initiates storage of the multiple sets of thumbnail data in a unit of storage of a repository. The unit of storage can be pre-allocated for storing the multiple sets of thumbnail data associated with the digital asset. Accordingly, in lieu of storing data for each thumbnail in a different file as in conventional methods, configurations herein can include storing thumbnail data in the same unit of storage or file. Thus, multiple sets of thumbnail data for a corresponding digital asset can be stored in a single file.
