resize your images to 800x600 with photoshop, there's no need to have bigger images then that, and nomatter where you upload your pics, they would load pretty quick & with bigger pics it loads slower.
p.s. how does the galary function on auctiva.com actually work? i know it costs money when u select it, but when u don't select it, in your standard ebay box of other items they have also no pictures? why is that? have i done something wrong? on the auctiva.com template of other listings no problem with the pictures, is this normall or have i done something wrong?
