Use thumbnails for professional-looking auction photos that load quickly.
If you’re hosting your auction photos [Hack #76] , you have the freedom to include as many full-size, high-quality images as you like at no additional charge. But you’re also responsible for inserting those photos into your auctions and presenting them in a way that is efficient and appropriate.
Now, large photos are more dramatic and eye-catching than small ones, but they also take longer to load, and including a lot of them will overwhelm the rest of the auction page (especially on small screens).
Thumbnail photos are much smaller than their full-size equivalents, both in physical dimensions and in the amount of data that must be transferred. This means that by replacing several full-size photos with thumbnails, your auction will not only appear tidier but will load faster as well.
Thumbnails are nothing more than smaller versions of full-size images, so you’ll need to make two versions of each photo.
