As subject says,
please change image size restriction of max. 640x480 px.
As those are only linked, and most images and screenshots are far bigger, please remove
the restriction or change it to something that allows most pictures to be linked, or at least to 1024x768.
Weird thing is that resctriction does not apply to uploaded images, which seems kinda inconsistent to me.
Also it would be nice to have options for [img] tag, to change the displayed size of bigger images,
but that would only be a bonus and is no priority.
