Minor Description
For now, the description is occupying 45% of the screen width, which means that most of the time it will be displayed on top of the image. The inconveniences resulted from this can be easily fixed by clicking on the image to hide the description, but this can be an annoying step if it is needed often.
Considering this, I propose as improvement to limit the width of the description to a 25% of the screen, along with a reduction for the caption font-size. This should limit the number of times the text overlaps with the image, or at least decrease the portion of the image which is not easily seen because of the description.
Also, right now the user ID and not the user name is displayed in the metadata section.
