Hmm, are you linking from the thumbnail of the picture? ;) Maybe that's why they're small?
Also, sometimes the links go bad & the pictures don't show up. Or it'll happen sometimes & then the pics will show eventually.
hmmm...that's weird might be something wrong with the system or even your computer..I know at times I can't view every picture, but if I refresh it most will show after that.
My pictures don't seem really huge unless I don't use the "Upload picture" button....if it says Horseforum.com on the bottom it shouldn't be that large...it should be medium sized.
My laptop acts crazy at times....there was one time when the "Index" button was four times the regular size but all the other links on top were the regular size
