Hello

I have put a GIF signature on my forum. Will this effect the upload speed on the website ans is there a maximum badwidth allowance on Forumotion?

I am using the image hosting site imageshack.

I don't think there's bandwidth limits for your forum but here's some other limits that you might find:

No, there isn't, put as many images and videos on there as you want.
