Well they are not but sometimes the connection makes it like that or maybe the browser you use? I don't know but I am sure not all of my GIFs are not fluid. Surely there must be some that are fluid to your taste? I assume.
Well GIFs are slides together. Only thing I can think of is when I cut some out to reduce the size of it.....like from 200 frames to 100 so it's not slow like you want to be fluid but more slow downed and less in size. Like that some of them I can post to show them since they have a limited size file here.
Well I still have improvements to do but at least I am one who does them and many just don't bother with them. That's too bad because many people look for some of them of different series like Ef A Tales of Memories for example.
The problem is not that you slowed them down, but that it feels like a bunch of slides of some similar (but not the same) images, which is exactly what it is if you think about it, but still...
Ummm... Anyway, don't mind me. I don't really know how to help you improve, and the onl reason I posted this at all was because I felt like I owe you this since I told you that your GIF's weren't good or something like that... Anyway.
