I'm Using The SFMLab Models,buy it's saying "invalid or Too Long,Is there a problem or is it too old?

I know, however, the big problem is the image size restrictions on Steam for large GIFs like this. It's either quality or speed that suffer if you try to post to Artwork Hubs. I could slow things down and reduce resolution or leave it as is.

Imo, having to read text off gif's makes it kind of inconvenient as you need to read the text on time before the next slide comes along and it could take 1 or 2 cycles, depending on the amount of text there is to fully read what was said on just one picture slide. This is tedious and takes more time to read through as opposed to just having the instructions as separate images you can read through at your own pace. Granted, you have left a good chunk of time to read each slide before they change, but it's still going to take a considerable amount of time for those users who may not have the ability to read as fast as you can.

Just throwing my 2 cents out there and while I can understand it probably isn't that easy explaining it in any other way besides showing a Gif and I feel not everyone really visits or knows the Guides Section exists.
