Microsoft Animated GIF Software

Many moons ago, Microsoft created and released as freeware a handy animated GIF (AGIF) program. Since it is in the public domain for use, I have included a copy of the version I have been using for years (download it here).

I run Norton antivirus and can attest that the MS-AGIF.ZIP file is clean as uploaded, but I advise you check it yourself prior to use.

Note that one trick to significantly reduce the overall file size is to not use full-size multiple images. You can create a single full-size GIF file as the primary image and then create smaller files that are only the parts of the base graphic that needs to change, and then specify it (or them) as additional images and assign an x/y value for where they are to be located.

I have created a brief "How-To" page to help you understand the technique. It is an AGIF that I created for MECA Electronics.

Graphical Banner Ad Pricing:

All banner advertisement slots are set up to accommodate 1, 2 or 3 ads that rotate into visibility on an equal basis, on average (a random number generator selects which ad is displayed). Banners remain in place until the page is refreshed or changed. Rates given are for occupying a slot at a 1:3 rate. If available, you are welcome to buy more than one instance in a slot - up to 3, which will cause your banner to be impressed with every page view. Terms include a minimum 3-month contract and up-front payment. All Graphical Banner advertising plans include the features of the Maximum Exposure Ad plan.

  • Upper 728x90-px Banner: $400/mo. (1:3)
  • Upper 160x600-px Banner: $350/mo. (1:3)
  • Upper 120x600-px Banner: $300/mo. (1:3)

Important Notes:

  • I do not collect page traffic or link click statistics for advertisements. Your website server statistical analysis is a much better reporter of inbound links from RF Cafe than I or anyone else can provide.
  • You must supply the banner graphic (JPG, PNG, or GIF format), with a file size no larger than 75 kBytes. If you have trouble meeting the file size, I will be glad to help - there has never been an instance where I couldn't meet it. A hyperlink will direct visitors to the URL you provide. An animated GIF is permitted sol long as its file size remains within the limit.
  • To the best of my knowledge the page layouts shown are representative of all pages on RF Cafe.
  • I make minor layout changes from time to time to test performance, but regardless of the layout, your ad(s) will retain relative positional integrity regarding top and bottom location.
  • * 78x26-px logos in upper right corner are provided at no additional cost, and are subject to size, location, and format change as deemed necessary for optimizing space usage. These only appear on the desktop display.
  • 3-month terms are offered for Maximum Exposure and Banner advertising plans. 6-month terms are offered for the Standard plan.
  • A 5% discount is available with a pre-paid 6-month commitment on the Maximum Exposure and Banner plans.
  • A 10% discount is available with a pre-paid 12-month commitment on All advertising plans.
  • Payment is required prior to ad runs.
