Best sizes when uploading image links on this site

By Jake yet again, in Fan Creations

Slightly off-topic for the creation forum I know, but i plan to upload some images to this site shortly and want them to come out the right size. What dimensions should I use for:

An expansion board about the size of Dunwich

Investigators

Large cards (e.g. Mythos Cards, Encounter Cards)

Small cards (e.g. Common Items, Spells)

Thanks.

I just overcame this issue myself for the Dreamlands Expansion I posted. I exported the SE files into JPG's. Then I loaded those JPG's into Photobucket. Then I took the direct link of those from there and pasted it into the Insert/Edit Image function in this forum. Then I just made the width to 600 and it took care of the rest. I hope this helps!
