How this category differs from its neighbours
What lands here stands for technology as a whole rather than one device: progress, automation, going digital. If you need a laptop, a phone or headphones, go to computer, mobile phone, headphones; for industrial and work gear, to equipment; for networks and connection, to internet. You come here when the object does not matter and the idea does.
What makes a file worth using
The transparency has to be real, not a painted chequerboard: check it on the image page by dropping a colour behind it. Edges should be clean, with no white fringe that shows up on dark. And no maker's marks on the case, no one else's interface on the screen — we filter such files out, but the catalogue is large, so tell us if one turns up and it goes.
Sizes and formats
An interface icon is happy with 200 px, an article illustration wants 800 px and up, print asks for 1500 px on the long side. Every image page carries an editor: add a background, trim the empty margins, change the size and save as PNG, WebP, JPG or ICO.
