Do you find websites use fewer words and more and more images these days? If so, you’re not alone. Icons, pictograms, glyphs and logos are replacing words to efficiently use space on small screen devices. I’ve looked for an official index of common use images to explain an internet picture language but none exists. The most useful I could find is Wikipedia
Further information about this phenomenon is explained by the Nielsen Norman group.
So all this to say, it’s important to also read what the image says and good web design should include a text indicator of what the symbol represents.
A few years ago the icon for WiFi was rarely seen and the Twitter bird that is used to re-tweet links became the modern day version of ditto marks. To those of us travelling and reading websites from other countries, the benefits are endless, however someone needs to keep track of this glyph language so we can understand each other!
If you’re really lost, you can try a Google Image search.
