A system provides on-demand digital assets hosting services to one or more users. The system receives a user selection of a digital representation (e.g., a digital image) of a digital asset, where the digital representation of the digital asset can be divided into multiple pixel blocks and the each pixel block represents a portion of the digital representation for purchase or donation. The system then tracks user's zoom level of the digital representation while the user browses the digital representation. Based on the zoom level, the method dynamically generates a zoomed version of the digital representation. Responsive to user selecting a pixel block of the digital representation and size of the pixel block, the system calculates the number of pixels contained in the selected pixel block, displays the selected pixel block and prepares the user to check out the purchase of the selected pixel block.
