The user needs to get an overview of multiple pictures without having to download each of the full size images.
A thumbnail is a miniature version of a larger picture. The thumbnail can illustrate anything graphical: a picture, movie or even a screenshot of a webpage.
The dimensions (width and height) of multiple thumbnails appearing next to each other are the exact same. In order to preserve the same proportions in the thumbnail image as were found in the original image, both resizing and cropping is part of the image manipulation process.
Common thumbnail sizes are:
|Dimension (width X height)||Description|
Using thumbnails provides the user with an overview of several images or movies in the space of one web page. Furthermore, thumbnails save bandwidth as the user does not have to click through all images to find the one he or she is looking for, but can be guided by the previews provided by the thumbnails.
I wish I had have come across this a while back when I came across this problem.
I had to display a thumbnail gallery but what was throwing me out was the differing dimensions of the thumbnails as the preserved the image width and height dimensions without cropping. I tried numerous differing approaches but it was very tricky to balance out the gallery.
Any tips on this would be very helpful.
