Most any animation on a website that stays fixed in one location is a sequence of .gif files. We create .bmp files in Paint programs and .jpg files with digital cameras or capturing off the internet. Apples and oranges right? You can convert .bmp files or .jpg files to .gif with specialized small programs, like Graphic Converter (www.graphic-converter.net
Before you do that you want to make sure the intended image does not exceed 100 pixels wide or 75 pixels high (same size as the thumbnails for airstreamphotos.com). Certain photographic programs can resize photos -- my small Canon's software didn't though.
Then I have used unFREEz freeware to sequence .gif images. I save that file to my desktop or a handy folder, then upload it to these forums at my 'user cp.'
