Scanner Chronicles: To Compress, or Not to Compress

We soon ruled out the photo file formats we hadn't heard of ~ a wise decision, in my opinion. We were getting to be old hands at Windows95, with enough shiny worn off of our brass to know that if we didn't recognize that extension, chances were, Windows wouldn't either. I knew from reading tutorials, as well as hellacious trials (or mostly errors) that .JPEG and .GIF formats were highly desirable for Web usage, but .BMPs weren't recommended. We did our first scan at 100 percent and were surprised to see the size of the nose on that painted dame! Re-sizing as a visual necessity was a given if we wanted to see more than one eyeball at a time without scrolling. It wasn't hard to resize, but neither of us knew enough about resolution or compression to know that these settings could affect the download speed of a file being fed from a web page. Nor did we know what "interlaced" meant. Of these options, we chose at least one of each, not knowing whether any of them would work for my intended purpose. Thus began my scanning career.
